Genealogy for Beginners

The ultimate beginners guide to genealogy
Marc McDermott

If the word “genealogy” brings to mind tedious searches through dusty shelves and boxes to eke out yet another tiny fact about a distant ancestor who died long before you were born, you’re right.

But you’re also completely wrong.

There is so much more to genealogy than just putting together a list of names, places, and dates.

Genealogy is all about understanding the history of your family.

It’s about where your ancestors came from, how their world affected who they were, how they lived, and eventually, how they came to have children and grandchildren and great-grandchildren, all the way to down to you.

People get started with genealogy for a variety of reasons:

  • to learn more about their family culture and heritage
  • to add a sense of history and tradition to their lives
  • to make sense of all the “cousins” they have met and figure out how they fit together
  • to find out whether that story that Grandpa Adams used to tell about being descended from President John Adams is really true
  • to leave a personal history behind for their children and grandchildren
  • and countless more

Whatever your reason for considering genealogy, this guide is designed to help you take that first plunge.

While this guide is specifically about genealogical research in the United States, most of the same rules apply no matter what countries you are researching.

What is genealogy

Genealogy is the study of our ancestors: our parents, their parents, and on and on.

But not only are we looking for a list of names and dates, we’re also looking for their stories and how they fit into history.

Genealogy is a lot like putting together a jigsaw puzzle, but without the photo on the box and with some of the pieces missing.

It’s challenging, but when you finally sit back and see the picture come together, it’s incredibly satisfying and rewarding.

Why you should start today

When I was 13 years old, all four of my grandparents and five of my great-grandparents were still alive.

By the time I was 23, every one of them was gone, together with their stories and memories.

The longer you wait, the more will be lost.

Records get destroyed, on purpose or accidentally; people pass away.

Too many people wait until they are retired, their children are grown, and they finally have free time, but that’s far too late.

Don’t wait, get started today!

Four tips for getting started

1. Organize your findings

Ready to jump right in? That’s great, but there’s something you should do before hitting the library or jumping online.

You need to decide how you’re going to organize what you find.

There are some ways you can do that, and none are perfect for everyone, so pick the one you think will work best for you.

On Paper

Regardless of what else you do, you should have a way to file physical documents.

Even if you plan to put everything on the computer, paper makes a great, durable backup, and can be great for organizing your thoughts, too.

Your best bet for paper records are file folders and somewhere to store them, like a file cabinet or storage box.

Use one folder for each surname you are researching. If you have a lot of information about a specific person or family, make a new folder just for them, too.

On the Computer

There are a variety of computer programs you can use to organize your genealogy, too. They range from free to rather expensive. See our guide here.

In general, the more a program costs, the more features it has. But for the beginner genealogist, more features isn’t always better.

Pick a less complicated program to start. You can always export your family tree from one program to another later.

Some websites, such as Ancestry and, allow you to build your family tree online and skip the software altogether.

Just be aware that if you use a subscription website to organize your data, you may need to keep paying every month instead of just once for software.

Probably the most popular genealogy program is Family Tree Maker.

It offers every feature you will need without going overboard, and there are how-to guides for it everywhere on the web.

Family Tree Maker retails for about $80, but chances are you’re never going to need anything it doesn’t offer.

2. Always use birth names

Whether you’re working on paper or a computer, one essential rule is to always use maiden names or birth names.

A woman’s surname may change two or three (or more!) times in her life, and you don’t want to have records lurking under several names.

Always use the surname she had at birth.

Likewise, if you have a child who is adopted, it is usually best to use his or her birth surname, too, if known.

3. Start with the census

Many folks just starting out in genealogy start with census records, and for good reason.

Most census records are now digitized, searchable, easy to access online, and full of great information to start building your family tree.

4. Don’t forget the bigger historical picture

Your life is a reflection of the world around you, and the same is true for your ancestors.

When it comes to genealogy, you cannot ignore the world that your ancestors lived in, either.

When your ancestors came to the United States, what was happening in the country where they lived before?

Was there a war, civil unrest, famine, religious persecution?

Why did your ancestors settle where they did?

Why did they move when they did?

All of these questions not only impact how and where you go about searching, but they also add historical context and interest to your family’s history.

For example:

  • many families relocated in the 1930s as a result of the Great Depression, looking for new opportunities
  • the U.S. government has issued land grants several times to encourage settlement of the “wild frontier”
  • the Irish Potato Famine in 1845-1852 caused thousands of people to emigrate

I even have one ancestor who settled where he did because he hurt his leg and couldn’t walk any further.

Understanding the world in which your ancestors lived is vital to understanding who they were, and making their lives truly come to life.

Bonus tip. Always be learning

One of the best things about genealogy is that you’re constantly a student. The more you learn and study the field of genealogy, the more addictive it becomes.

It’s important to stay up to date with the latest news, especially as it relates to the big genealogy sites releasing new digital record collections. 

There are countless sites out there to follow. One website in particular that we love is Genealogy Explained.

Common records

There are more than a dozen kinds of records commonly used in genealogy (and many uncommon ones, too).

Each type of record will be good for certain types of information, but less useful for others, so it is important that you know about all of them.

Many of these records can now be found online (check out the website list later in this guide), but for some, you still need to go to the source, whether it be a courthouse, a church, a library, or wherever.

Census records

What Is the U.S. Census?

When we talk about the census, most of the time we’re talking about the Population Schedule of the U.S. Census.

This census has been taken every ten years since 1790, and most of the records still exist today (unfortunately, most of the 1890 census was lost in a fire).

While other components of the census sometimes exist, such as an Agricultural Schedule or Manufacturing Schedule, most of the time the Population Schedule provides the greatest amount of information for genealogists and family historians.

Information Available from the Census

From 1790 to 1840, census takers listed the name of the head of each household, together with the number of people living in each household divided into age ranges and by sex.

Unfortunately, that means that these records may be of limited use in tracing family lines, as there is no way to connect children with parents or even husbands with wives.

Still, these years can help you track your ancestors’ movements over time, and may give clues on where to search for other, more detailed records.

Beginning in 1850, the census lists every single person in each household, including valuable information such as place of birth and age.

Later records list actual month and year of birth, or even exact date of birth, depending on the census.

1860 U.S census (click to enlarge)

They may also list occupations, places of work, income, the value of real and personal property, education level, and more.

In general, the later the census, the more information it includes.

But any census from 1850 on can be a very helpful resource in linking parents with children and trace elusive ancestors through their brothers and sisters.

How Information Was Gathered

One of the most important considerations in using census records is understanding how the information was gathered.

The Theory: during a certain range of days, a census taker visited every single house or another dwelling within his territory, spoke with the people living in each, explained what information was needed, and carefully gathered and recorded it.

The Reality: although the vast majority of the information on the census is accurate (or very close) there are several reasons why a particular record might not be.

One of the most common reasons was that no one was home.

If the residents weren’t home, rather than having to circle back—and keep in mind most years of the available census, people traveled on foot—the census taker likely got the information from the next door neighbors.

Beginning with the 1940 census, the census takers were finally instructed to indicate who provided the information (with a plus sign inside a circle), but that doesn’t help in any of the years before that.

1940 U.S census (click to enlarge)

Even if someone was home, they might not have understood all the questions, they might not have remembered their children’s exact ages (or even their own), they might not have spoken English well (or at all), and they might have been entirely illiterate, which led to some very interesting and creative spellings of names.

And of course, it doesn’t matter how correct the information is if the census taker’s handwriting is illegible.

Fortunately, even if not exact, in most cases the information is close, and may provide the clues needed to lead you to more accurate and thorough records.

Just try not to be frustrated when your ancestor John appears as Johnny, age 5, in 1850; Jon B., age 14, in 1860; and J. D., age 26, in 1870.

Census Date

One thing to keep in mind is the date that the census was taken.

Historically, census information was collected over a period of a month or more, but every census year had a specific date (such as April 1), and all information was supposed to be based on that date.

1940 U.S census residence section

So if Susan turned 13 on April 5, and the census date was April 1, she should still be listed as age 12 on the census, even if the census taker didn’t arrive until after her birthday.

If someone in the household was alive on April 1 but had passed away by the time the census taker arrived, they should still be listed on the census.

In reality though, things did not always work out that way. Susan was listed as age 13, and the deceased was nowhere to be found on the census.

To make matters worse, the official census date has not stayed the same.

From 1830 to 1900, the date was June 1 (actually June 2 in 1890, because June 1 was a Sunday).

But in 1910, the date was moved to April 15. In 1920, it was moved to January 1. In 1930, it was changed to April 1.

Be aware of the official census date and how it might affect your search.

Places Change

From one census to the next, your ancestors could be living in a new township, a new city, a new county, or even a new state, all without moving an inch!

That’s because places change over time.

A town may adopt a new name.

A county might be split in two.

New states were being formed even into the 1950s.

You need to be aware of this, and may need to do a little research to find out what a location was called in a certain year.

For example, searching for your ancestors in Snyder County, Pennsylvania in 1850 is guaranteed to turn up zero results, because Snyder County was not formed until 1855.

You need to be searching in Union County instead.

Searching with Soundex

It is very easy to misspell names, especially if the person saying it is illiterate and can’t spell it for you.

And for much of U.S. history covered by the census, many Americans were illiterate. Foreign names and those spoken with a heavy accent were also often misspelled.

So if you’re looking for an ancestor with the surname Donovan, how can you possibly search for it on the census if it might have gotten spelled Donavan, Dunavan, Dunovan, Donnovan, or any of a dozen other ways?

Soundex is a special system that was set up to help you do just that by organizing similar sounding names together (such as Smith and Smythe).

In the 1930s, Soundex indexes were created for the 1890 to 1920 census schedules, and have since been created for many other records, too.

Some genealogy websites such as Ancestry even include an advanced search option to use Soundex when searching any of their records.

Soundex uses a letter (the first letter of the last name) and three numbers representing additional consonants, if any, to group the names (Smith, for example, becomes S530; Washington would be W252).

It lumps similar sounding consonants together (like d and t, or m and n) to make it easier to catch spelling mistakes.

Many times, this can help you find missing ancestors, especially if their names were misspelled on the census or other records.

However, the more unique your ancestor’s surname, the less useful the Soundex might be.

Galloway and Galey, for example, both share the same Soundex code, G400, but there are many, many more Galloways than Galeys.

We’ll go into more detail on using Soundex (and the related Miracode) in another article.

Is it Worth It?

Given all the problems of finding specific census records and considering that the information may not be correct, is it even worth using them at all?

Absolutely, without question, yes.

While the census may have its issues, it is very easy to search.

Every available page of every year has been digitized, indexed, and put online by sites such as Ancestry and, making them accessible from nearly anywhere, often for free.

Census records are one of the few good sources for locating and tracing parents, siblings, and families across generations.

They provide excellent clues about not only places and dates of birth, but tell you exactly which counties you should be searching for wills, probate records, birth, marriage, and death records, church records, and so much more.

The census isn’t going to give you everything you want to know about your ancestors, but it is a fast, easy, and inexpensive way to get started.

Quick Tip: in some census years, a few people on each page were chosen to provide extra information – be sure to check the bottom of the census sheet, and you might get lucky. More on the U.S. census here.

Other common records

Here’s a quick rundown on the other types of records used most often in genealogy.

Birth certificates

Birth certificates can tell you not only when someone was born but where, and give important details about the child’s parents, often including when and where they were born, too.

Birth certificate for President Obama

Some states have them online, others you may have to request by mail.

Before around 1900, many birth records were kept by counties rather than the state.

Death certificates

Death certificates will include date and place of death, the cause of death, and very often information about either the decedent’s spouse and family, parents, or both.

Like birth records, most have been kept at the state level since around 1900 and the county level before that, and many are available and searchable online.

Social Security Death Index (SSDI)

The Social Security Death Index tells you the date of death, date of birth, when and where the SSN was issued, and the city where benefits were last paid.

It is fully searchable online and easy to use. However this only helps for those ancestors who had Social Security Numbers issued, so it isn’t much help before 1950, and somewhat incomplete up to around 1970 or so.

Marriage records

Marriage records include the date of the marriage, the age (and sometimes date of birth) of those being married, and often their parents’ names.

In many cultures, the place of marriage could be a great clue to find the bride’s birthplace as the marriage often took place in the same town.

They may also include lists of friends or relatives who were witnesses for the marriage.

Counties and states maintain marriage records, and many are now digitized and online.

Churches maintain marriage records too, and before the mid-1800s, that might be the only place that kept them.

Don’t forget to search local newspapers for marriage or engagement announcements, too.

Baptism records

Baptism records will list the date of the baptism and, for children, the child’s parents. It may also list the date of birth.

These are mostly only found in church records.

Baptism record of President Martin Van Buren

Wills and probate records

These records vary widely in the information they contain, but can be great sources for names of children or other relatives, and clues about where to look for property or other records.

They’re mostly only found in county courthouses. Sometimes indexes are published online or by local genealogical societies.

Deeds and land records

Deeds and other land records track land ownership, and will list the name of the buyer and seller as well as the date.

They can sometimes help trace family lines, but are most useful in proving residence in a particular county.

They’re mostly only found in county courthouses, though some counties have started to put them online.

The Bureau of Land Management ( has over 5 million federal land title records searchable online, from 1788 to the present.

Passenger lists

If your ancestors emigrated to the United States, they had to get there somehow, and for most of history, that meant a ship.

Passenger lists generally list every passenger, so they are good for linking spouses and children, and often list ages, too.

Be sure to check the columns to see who paid for the trip, last known address/contact person, and who they were going to stay with in the U.S.

These columns often reveal invaluable information about close family members.​

Many passenger lists are now online. Your local genealogical library may also have a copy of Filby’s Passenger and Immigration Lists Index, which before the internet indexed every passenger list that was published in a print source.

This index can also be found online at, but requires a subscription.

Naturalization records

Once your ancestors arrived, they likely wanted to become citizens.

Applications for naturalization can include great information including name, date of birth, place of birth, date, and place of immigration, and more.

Many of these records can be found online, or check out county, circuit, or district court records.

Draft cards

Several drafts have taken place in U.S. history, and even if your ancestor never served in the military, he might have had to fill out a draft card.

They can give you name, date, and place of birth, place of residence, and even sometimes a physical description.

Records from the 1942 draft are available online. For other drafts, check out the National Archives and Records Administration (

City directories

Before there were phones and phone books, there were city directories.

These can tell you not only where your ancestors lived, but their occupation as well.

Some city directories are available online, while others can be found in local libraries.

Family bibles

If you can track down an old family bible, you may find a treasure trove of genealogical data.

Families often recorded every birth, baptism, marriage, and death in their family bible, sometimes for several generations.

Check with all your living relatives to see if there is a family bible lurking on a bookshelf or in a closet somewhere.


Obituaries vary a lot in what they include, but often list not only the decedent’s full name, date of birth, and date and place of death, but also their parents, spouse, children, and grandchildren, and their spouses, too.

There are a variety of obituary indexes online, such as and

Specific newspapers can be searched, too, either through the newspaper’s site or at

Cemetery records

Cemeteries keep records of every interment which may include a lot more information than you think, including not only date and place of death but the place of birth, parents, spouse, and even names of children.

Some cemeteries have their records available online, but many you will need to contact them individually.

There are no formal indexes of cemetery records online, but one great source to start with is


Once you’ve found your ancestor’s grave, the tombstone can provide some helpful hints including dates of birth and death, spouse, and sometimes children.

Photos of many tombstones are available at, but the best way is to visit the cemetery yourself.

It helps you feel a direct connection with your ancestors.

Just as important, going in person gives you the chance to check other graves nearby.

Sometimes several generations of a family were buried within a few feet of each other, so be sure to check out nearby tombstones as well.

Old family photos

Names, dates, and places are all well and good, but if you can put a face with a name, that’s a thousand times more satisfying.

And finding photos of your ancestors may not be as hard as you think.

The best place to start of course is with your own family. Reach out to every relative you can and see what they might have lurking in their photo albums.

Even if they don’t have photos, they may know which family member does have them and point you in the right direction.

Most genealogy websites allow you to do photo searches, too, though their collection size can vary a lot.

One site called not only lets you search for photos, but offers to send you a free copy if you find a direct ancestor.

Others places you might find photos include:

  • newspapers
  • military records
  • business directories
  • passport applications
  • prison and hospital records
  • the Library of Congress photo collection

Many libraries and historical societies have photo collections, too.


Written records are not the only source of information; one of your best sources is other family members.

Talk to your family, especially older relatives, and you will be amazed at some of the stories you learn.

Personal stories add texture to your ancestors, fleshing out those names and dates into real people.

Interviews can also help you understand why some records contradict.

For example, on one census I found a cousin (Edward) who was listed as my great-great-grandfather’s son, but on the next census, Edward was listed as his grandson.

By talking to a great-aunt, I came to learn that Edward was my great-great-grandfather’s grandson, but because his mother was unmarried when he was born, they pretended Edward was their son for several years to avoid embarrassment.

There are three big keys to interviewing:

  • the sooner, the better – if you wait too long, those stories may vanish forever
  • record the interview – on tape, or digitally, you’re going to want to listen to it again. Better yet, record it on video – imagine how pleased your grandchildren will be to watch their great-great-great-grandfather telling family stories 50 years from now
  • prepare questions ahead of time – if you don’t know what you’re after, the interview may break down into rambling, disjointed stories

Where to find common records

Online resources

There are literally hundreds of thousands of websites dedicated to genealogy and family history, but not all are created equal.

Here is a rundown on some of the most important and useful websites for your research. To learn more about free resources, check out our guide to free genealogy websites.


Ancestry has thousands of data collections available online, containing millions of individual records.

It also lets you build your family tree directly online, or upload a family tree from your computer.

Once your family tree is online at Ancestry, it will try to find common ancestors with other users who may have already done a lot of the research on your family themselves.

Be warned, sometimes these other family trees are quite useful, but sometimes they are poorly done, and can even set back your research if you don’t verify their information.

Ancestry is only available by a paid subscription, but most public libraries have a subscription, so you can go to the library and use theirs. is operated by the Family History Library in Utah, and provides access to all of their records that have been digitized so far.

Like Ancestry, FamilySearch lets you build your family tree online and connect with other existing trees.

FamilySearch is entirely free for anyone to use.


If you plan on doing any research in the British Isles, FindMyPast is a must-have tool.

They have the largest collection of English, Scottish, Welsh, and Irish records available anywhere, extensive newspaper collections covering 21 countries, and millions of records not available anywhere else.

Click here to read our review of FindMyPast. has digitized more than 5,000 different newspapers stretching as far back as the 1700s, and is constantly adding new images (they are already at 280 million newspaper pages!).

Many local newspapers included birth, engagement/wedding announcements, social gatherings, obituaries, and more.

You may even find a drawing or photo of your ancestors if you’re lucky. does require a paid subscription, but currently offers a seven-day free trial so you can test it out first.

Some libraries maintain a subscription to the site, too.

Fold3 specializes in military records from the Revolutionary War to the present.

If your ancestors ever served in the military, you have a good chance of finding them there.

Fold3 not only includes official records, but photos, stories, and personal documents as well.

Fold3 offers both free and paid memberships, but many of its records require a paid membership to access.

Find A Grave is a great site for doing just that, finding the graves of your ancestors.

There are over 160 million grave records currently available, with more being added all the time.

In many cases, there are even photos of the headstones. If not, you can place a request for a local genealogy buff to photograph it for you – for free!

The site also includes forums where you can ask all your grave hunting questions.

Find A Grave is free to use.

If you are looking for a genealogy site, any genealogy site, you can find it on Cyndi’s List.

Cyndi’s List is one of the oldest genealogy sites on the web, and potentially the most useful.

It basically lists every genealogy site on the web.

Yes, every single one (over 320,000 at the moment).

And it is constantly updated as new sites appear and old ones vanish.

Cyndi’s List is organized in several ways, letting you find the sites you want quickly.

It is great for identifying specialized websites for specific countries, states, counties, interests, types of records, and more.

Cyndi’s List is free, but donations are always welcome.

Offline resources: records repositories

While genealogical records are available online more and more often these days, don’t limit yourself to just computer searches, or you will miss a lot.

There are several important repositories that house millions of genealogical records, and you should be familiar with them.

Just as important as the records, these repositories have librarians and genealogy experts who can help you narrow your search, navigate tricky records, and find what you want, often for free!

Family History Library

The Family History Library houses the largest collection of genealogical materials in the world.

The main library is located in Salt Lake City, Utah, but there are more than 2,000 branch locations, called Family History Centers, located all over the world.

Family History Library Salt Lake City, Utah

Every Family History Center has dedicated, experienced staff who are ready to help you plan out and conduct your search.

Each center has its own collection of local materials and access to billions of digitized records online.

Also, if something hasn’t been put online yet but is in the Family History Library collection, you can request it to be delivered to your nearest center for local use.

This includes books, magazines, microfilmed documents, and more.

For more information about the Family History Library and to search their online collections, visit

National Archives

The U.S. National Archives, located in Washington, DC, houses a wealth of documents of interest to genealogists.

National Archives in Washington D.C.

Examples of records you can find in the National Archives include:

  • military records from the Revolutionary War to the present, including pension files and casualty lists
  • passenger lists
  • census records from 1790 to 1940
  • naturalization records for those who became American citizens in a federal court
  • American Indian tribal rolls and related records
  • passport applications
  • federal land grants
  • and much, much more!

While many of these records are now available online, many others are not.

A trip to the National Archives can help you learn a lot, but only if you plan ahead.

Examine the online indexes ahead of time to see what records you will want to access. This will save you lots of time and headaches during your visit.

There are also several Federal Records Centers associated with the National Archives around the country.

One of these might be a much closer, less expensive trip if they have the records you need.

State libraries

Each state maintains a state library, and they are often a good place to start looking.

Most state libraries have special genealogy sections and staff members to help with your research.

Some records that you can expect to find at state libraries include:

  • U.S. census records
  • state census records, if the state ever did its own census
  • state and county histories that can fill in the story about where and how your ancestors lived
  • many county histories published in the 1800s had extensive biographical information about people living in the county at the time
  • newspapers from across the state, both print and microfilm, often going back into the 1880s or even earlier
  • family history books and genealogies privately published by state residents
  • journals and newsletters from genealogical societies within the state

Local libraries

Your local library may have more than you think, especially if your family has lived in the area for several decades.

But even if they haven’t, keep in mind that wherever your ancestors did live, there was a local library there, too.

Local libraries are great resources for:

  • local newspapers that may not be held at the state library
  • local histories, published or unpublished
  • clippings files – many libraries clip out important newspaper articles and sort them by topic; in many cases, they have clippings files for important local surnames, too!
  • general history resources you can use to learn more about your ancestors’ world

One very important “local” library for genealogists is the Allen County Public Library ( in Fort Wayne, Indiana.

This library’s genealogy collection is second only to the Family History Library.

While you may not be able to travel there, if you find something they own that you need, you might be able to access it through interlibrary loan.


The county courthouse where your ancestors lived likely contains some valuable records that may not be found anywhere else, such as:

  • birth and death certificates (especially before 1900)
  • marriage certificates and divorce decrees
  • adoption records
  • deeds or other land records
  • wills and probate records
  • some military service records
  • tax records

They are also the place to look for court cases, too, whether your ancestor was a plaintiff, defendant, or witness.


Finding the right church to search for your ancestors’ records can be tough, but it is often well worth it.

In many cases, especially before the middle of the 19th century, churches were the only repository for certain records, including baptisms and marriages.

But in some cases, they might be your only source for births and deaths, too.

They may also include when your ancestors became members or transferred to a different church, helping you trace what years they lived in the area.

Unfortunately, most church records are not available online.

Worse, many of them have been lost over the years to fires, floods, or simple neglect.

Still, the rewards can certainly be worth the effort.

Genealogical societies

Every state, nearly every county, and even many towns have a genealogical society.

State genealogical societies will carry many of the same kinds of records as state libraries.

County and local genealogical societies are excellent sources for records from a specific area, including those that you won’t find anywhere else, like high school commencement programs as an example.

Best of all, local societies have local experts, folks who may recognize your family name, and may even have done research on it.

Most genealogical societies also publish a journal or newsletter with tidbits gleaned from print records that don’t appear anywhere else.

Searching outside the United States

Chances are at some point you are going to trace your ancestors back to when they arrived in the United States.

You could stop there, but where’s the fun in that?

Every country has organizations and resources similar to the ones already mentioned.

Some of them, such as county courthouses, local libraries, genealogical societies, and churches, are going to be nearly identical in what records they hold.

There are too many national archives to list here, but a web search should quickly pop up the ones you need to keep digging further into the past.

DNA tests

Over the last ten to fifteen years, DNA tests have become a popular way to pursue ancestors and locate long-lost family branches.

But how do they work, and what do they actually tell you?

There are three types of DNA tests, and they all tell you different things.

  • Autosomal DNA looks at how similar certain sections of DNA are to other living people, and works best to locate cousins and others who are related to you within the past four to five generations.
  • YDNA testing examines only the Y-chromosome, so it only works in men, but can trace a male line back for many generations. YDNA is only passed from father to son (ie your father, your father’s father, and so on…)
  • Mitochondrial DNA (mtDNA) testing can also trace a line back for many generations, but only a maternal line. mtDNA passes from a mother to all of her children (not just sons) and applies only to that one female branch of the tree.

If you are trying to verify that you are related to a specific ancestor, then the YDNA (for a male ancestor) or mtDNA (for a female ancestor) are the way to go.

Note that since only men have a Y-chromosome, women who want to use the YDNA test will need to have a close male relative, such as a father or brother, take it for them instead.

Y-DNA tests are particularly useful for people whose ancestors changed their surname at some point in time. 

The test used most often in genealogical research is the autosomal DNA test, because it is the most useful for linking you with close living relatives.

How does DNA testing work

  • You order a kit
  • You use the kit to collect a DNA sample (either a saliva sample or cheek swab)
  • You return the kit to the lab, which creates a genetic profile
  • In roughly six to eight weeks, your results are emailed to you

An autosomal DNA test can help your genealogical research in two ways:

  • It gives you a general idea of your ethnic background – that is, the regions from which your ancestors came
  • It can connect you with others who have been tested and are a close match

Keep in mind that autosomal DNA is a merger of DNA from both of your parents.

The further back you go, the more mergers have taken place.

Because of that, an autosomal DNA test is only useful for those related within about five generations (third cousins or closer).

On the other hand, mtDNA changes extremely slowly.

If your mtDNA is identical to someone else’s, that proves that you have a common ancestor – but that common ancestor could go back 50 generations!

DNA testing companies

For the purposes of this guide, we’ll mention three companies that do genealogical DNA testing. Use our guide for more information on the best DNA tests.


  • Only offers autosomal DNA testing
  • Lets you link your DNA results to your Ancestry family tree (requires a paid Ancestry subscription)
  • Lets you connect with others who share the same DNA markers if they have made their results public

  • You can choose from any of the three tests
  • You have the option of using a tool to connect with others (but only if they are using it, too)
  • Considered the most accurate for determining regions of origin through mtDNA or YDNA testing
Family Tree DNA

  • You can choose from any of the three tests
  • Lets you contact and be contacted by everyone with matching markers
  • Allows you to upload data from tests run by other companies
  • Considered the best overall by genealogists for autosomal DNA tests

Costs vary depending on the company and specific test done, but expect your test to run about $80 to $200 on average.

Genealogy TV shows

It seems like there’s a TV show for everything these days, and genealogy is no exception. In fact, there are several.

Watching the methods and resources used in these shows can be a great introduction for beginner genealogists.

Finding Your Roots

Produced by PBS and now in its third season, Finding Your Roots delves into the genealogy of guest celebrities.

The show uses a variety of methods to trace its guests’ family trees and identify some previously unknown (and unexpected) ancestors and relatives.

Here’s a great clip with guest, Anderson Cooper:

Finding Your Roots can give you a good overview of different methods genealogists use in tracking down information.

Who Do You Think You Are?

Who Do You Think You Are first aired in Great Britain in 2004, and has now gone through thirteen seasons.

Not only that, it has gone on to ten other countries as well, including the U.S., where a show of the same name airs on TLC.

Like Finding Your Roots, Who Do You Think You Are features a different celebrity guest on each episode and uses a range of genealogical methods and resources to trace their family histories.

Here’s a great clip from the Courtney Cox episode where she discovers her royal blood:

Long Lost Family

Long Lost Family is another show that first started on the BBC, but has since come to the United States as well.

The show uses genealogy to connect relatives who have never met one another before.

The people featured in the show are not celebrities, but everyday folks who have been searching in vain for years for their missing relatives.

Here’s a great clip from a recent episode:

Genealogy Roadshow

Another PBS offering, Genealogy Roadshow visits historically important locations, where the hosts help those with specific genealogy problems find their answers.

Here’s a preview of season three:

Books and magazines

There are far too many helpful books and magazines to list them all here, so I’ll just offer a few suggestions. For more, read our guide to the best genealogy books.

Before you start shopping, though, be aware that you can spend hundreds, even thousands of dollars on genealogy books if you’re not careful.

And chances are you’ll never use half of them.

So here are my general recommendations:

Get one good basic guide, such as Genealogy for Dummies.

Buy one guide for organizing your research, and one for documenting it

Then stop, and consider the states or countries you expect to research.

If you know you are going to be doing a lot of research on a specific area, consider picking up a guide for that area.

And that’s it.

Stop there for now.

You can always buy more later, or, to save money, borrow them from the library as you need them.


Here are a few books that I highly recommend. There are many other good sources out there, but these are ones I know are great.

Genealogy for Dummies: a good overall guide, easy to use, and covers all the basics

Evidence Explained: Citing History Sources from Artifacts to Cyberspace by Elizabeth Shown Mills – documenting your sources is essential in genealogy, and this comprehensive guide shows you how

Organizing Your Family History Search by Sharon DeBartolo Carmack – helps you plan out your genealogy searches in advance, saving countless hours of wasted time

Long Distance Genealogy by Christine Crawford-Oppenheimer – find and obtain documents and family records from libraries, archives, family history centers, microfilm, and the internet, all without leaving home

Courthouse Research for Family Historians by Christine Rose – helps you navigate the often confusing but vitally important records located in county courthouses

Organize Your Genealogy by Drew Smith – once you’ve gathered all that information, this guide helps you get it all organized


As with books, there are countless magazines dedicated to genealogy and family history.

Here are just a few of the most popular:

All of these have websites, so you can get an idea of what they cover.

They are often available at your local library as well, especially if it has a genealogy section.

Hiring a professional

Not sure you want to do all the work yourself, or that you even can?

You might consider hiring a professional, but it will cost you.

On average, rates vary from $35 to $60 an hour, plus expenses.

In most cases, the only time you should need to hire a professional genealogist to help you is if:

  • you’re super rich and don’t want to do the work yourself (where’s the fun in that?)
  • you’ve hit a roadblock, and you just don’t know what to do next
  • you need to do in-depth local research, and it’s too far to travel yourself
  • you need an expert to translate records from a foreign language
  • you want expert help to compile a print genealogy or family history

If you do decide to hire a professional, you should look for one who has been accredited by one or more bodies.

You can find lists of accredited genealogical researchers at:

Final thoughts

So there you have it, everything you need to get started on what for many is a lifelong hobby, and for some even a profession.

It may seem daunting at first, but it only takes a few minutes to get started.

And once you start connecting with your ancestors and your family’s history, you will never want to stop.

But remember, the most important thing is to start now.

Happy hunting!
