Best DNA testing kits reviewed

1. AncestryDNA

The best DNA test for genealogy, AncestryDNA has the most extensive database (15 million customers) so you’ll find the most DNA matches there.

Ancestry DNA test kit

What we like:

  • Database of over 15 million customers for matching
  • Strong genealogical community
  • Connect with matches through anonymous email and message boards
  • Link your DNA results to your online family tree
  • No subscription required

What we don’t like

  • Viewing family trees of your matches requires a subscription
  • Does not allow raw data uploads from other sites

Read our complete AncestryDNA review.

Note that you do not have to have an Ancestry subscription in order to take their test or see your results. You also do not need a subscription to build your own family tree.

A subscription allows you to view genealogical records, view the family tree’s of your matches, and compare your tree with your match to find common ancestors.

There are of course many other features on the research side of your genealogy. Get a 14-day free trial here.

2. MyHeritage DNA

The best DNA testing kit if you’re looking for matches outside the United States, MyHeritage has the largest database of international customers. They also offer some pretty neat tools such as auto clustering and a chromosome browser.

MyHeritage test kit

What we like:

  • Largest database of international customers to be matched with
  • Link your DNA results to your online family tree
  • Allows free upload of raw data from other sites
  • Covers 42 ethnic regions

What we don’t like

  • Relatively small (but rapidly growing) database compared to other sites. Currently 3.8 million

3. 23andMe

23andMe is the best test kit for dedicated genetic testing for health. Since most people who test there aren’t as interested in family history or communicating with DNA matches as compared to sites like Ancestry, 23andMe would probably not be my first choice for genealogy.

23 and me DNA test kit

What we like:

  • The best company for health and wellness reports
  • Has a large database of more than 10 million customers
  • Includes a chromosome browser for comparing results

What we don’t like

  • Very limited genealogical community compared to other sites
  • No Y-DNA or mtDNA matching
  • Does not allow upload of raw data from other sites

Read our complete 23andMe review.

4. FamilyTreeDNA

The best DNA test for distant ancestry (beyond 6-8 generations), and paternity testing. One major perk is, even if you do get your testing done by a different company, FamilyTreeDNA lets you upload your raw data into their system as well.


What we like:

  • Only company to offer all three tests separately
  • Only company to offer Y-DNA and mtDNA matching
  • Cheek swab DNA collection (much easier for babies and elderly)
  • Allows free upload of raw data from tests run for other sites
  • Has a chromosome browser, which lets you compare two or more sets of DNA results to see segment overlap
  • Surname, haplogroup and other group projects you can join

What we don’t like

  • Has a smaller database of people than sites like Ancestry (since it’s not as popular to the mass market), so you might miss some matches
  • Very broad ethnicity regions

Read our complete FamilyTreeDNA review.

5. Living DNA

If you have any British or Irish ancestry, you’ll definitely want to do an ancestry test with LivingDNA. Based in the UK, LivingDNA specializes in “high definition” genetic testing in the British Isles and can narrow into the exact regions of your ancestry in the British Isles.

Because of the lack of a customer database (and matches), I would also test with another company in addition to LivingDNA.


What we like:

  • Divides the UK and Ireland into many more, smaller regions than other services

What we don’t like

  • No separate autosomal DNA only test, so highest overall price
  • Almost no database for matches

DNA testing buyer’s guide

In this guide:

For centuries, genealogists have relied on oral and written records to trace their family trees. But around the year 2000, the age of genealogical DNA testing was launched. This provided genealogists and family historians with an opportunity to use well-established scientific methods to prove relationships and ancestry.

Compared to paper records, which may be incomplete or inaccurate, DNA testing is precise. But is it right for you?

And if so, which test is right for you? How do you take it? How much does it cost? Which company should you use?

What is DNA?

Before we jump into DNA testing, let’s talk about what DNA is.

DNA, or deoxyribonucleic acid, is found in every living cell everywhere. It is a long chemical chain that tells our cells how to grow and act.

DNA is divided up into chromosomes, or major blocks, which are in turn divided into genes.

Humans have 23 pairs of chromosomes (46 in all) arranged in a double helix.

We each get 23 chromosomes from our mother and 23 from our father.

In humans, the 23rd chromosome is either an X-chromosome or a Y-chromosome, and determines if we are male or female.

Women have two X-chromosomes, while men have one X-chromosome and one Y-chromosome.

It may sound a little confusing, but this is important to understand, because there are different types of DNA testing.

Types of DNA tests

There are three main types of DNA tests used in genealogy.

Each one works a little differently, and tells you different things.

Naturally, that means that each one has its advantages and disadvantages.

Autosomal DNA tests (atDNA)

autosomal DNA inheritance chart
Autosomal DNA tests are the most popular and look at the DNA you inherited from every line in your family tree. This test provides an estimate of your ethnicity – or the regions of the world where your ancestors lived within the past few hundred years. This test also matches you with distant relatives.

Autosomal DNA (atDNA) is that DNA that does not contribute to gender; in other words, the first 22 pairs of chromosomes. It is inherited from both your maternal and paternal ancestors.

Because it does not rely on the 23rd chromosome, atDNA tests can be done in both men and women with the same results.

What is an atDNA test?

atDNA tests are by far the most popular for consumers. This is the test that gives you ethnicity estimates as well as family matches.

This test examines single-nucleotide polymorphisms (SNPs), or the different “shapes” of individual nucleotides, small chunks of DNA.

Genealogical atDNA tests examine about 700,000 SNPs to determine how closely related you are to someone else.

Remember that half our DNA comes from our father and half from our mother.

Going back in generations, that means that roughly one-fourth of our DNA comes from each of our grandparents, one-eighth from each of our great-grandparents, and so on. These percentages are never exact since DNA inheritance and recombination is completely random.

The further you go back, the less DNA you have inherited from a particular ancestor, and the harder it is to prove that you are related.

So autosomal DNA tests are only useful for about 6-8 generations.

What It Tells You

Most people who do an autosomal test do so for ethnicity estimates. Autosomal tests will give you a set of ethnicity results based on how your DNA compares to reference populations created by the testing company.

For genealogical purposes, the main use of autosomal DNA testing is to find relatives and determine how closely related you are to someone else.

This can be especially useful if you know very little about your parents or grandparents and are having a hard time locating living relatives.

Many times, relatives located by the test are researching the same family lines as you, and you can share research with them.

Every company mentioned in this guide offers autosomal DNA tests. Again, it is by far the most popular test for consumers.

Mitochondrial DNA testing (mtDNA)

mitochondrial dna inheritance
Mitochondrial DNA (mtDNA) is passed down from a mother to all her children (both male and female) and examines your direct maternal line only. Like Y-DNA, mtDNA changes very slowly over time so you can trace maternal lines back thousands of years. This test should not be confused with X-DNA analysis.

mtDNA is genetic material inside mitochondria, small components found inside every cell and which have their own separate DNA strands.

mtDNA is passed down exclusively from females. Both males and females inherit their mtDNA from their mothers, therefore anyone can take this test.

Because mtDNA does not include a combination of DNA from both parents, it does not change with every generation.

In fact, mtDNA changes extremely slowly – it might remain exactly the same for dozens of generations!

How It Works

While autosomal DNA testing looks at the 22 pairs of autosomes inside the cell nucleus, mtDNA testing looks at the DNA inside the mitochondria which exists outside the cell nucleus.

Among other things, that means the test only has to examine about 16,500 genetic base pairs, instead of the 3.2 billion base pairs found in our DNA.

The test normally looks at only specific portions of the mtDNA and compares them to established samples.

What It Tells You

mtDNA gives very precise and accurate ancestry results, but only for the maternal line.

results, but only for the maternal line.

That is, it tells you about your mother’s mother’s mother’s mother, and so on, back through time.

But it can’t tell you about any of your other ancestors, such as your mother’s father or any of your father’s ancestors.

An mtDNA test will also identify how closely related you are to a haplogroup.

A haplogroup is basically a group of people with a single common ancestor.

Historically, everyone living in the same region might belong to the same haplogroup, or very closely related ones.

This means that your haplogroup can identify where your maternal line originated.

It could also help you locate distant relatives, but some of them could be very distant (thousands of years).

In some cases, mtDNA can remain nearly identical for 50 generations or more. This makes it difficult to use mtDNA matching for genealogical purposes. A perfect match means you are related, but you might be 48th cousins!

The only company to offer individual mtDNA kits is FamilyTreeDNALiving DNA  and 23andMe bundle very basic mtDNA testing with their autosomal DNA test.

Y-DNA tests

Y-DNA inheritance
Y-DNA Tests look at the Y-chromosome (only found in males) which is passed from father to son and changes very little over time. This allows you to trace the direct line back thousands of years. Females don’t have a Y-chromosome so they cannot take this test. However, they can ask a male relative (i.e. brother, father, uncle, etc.) to take the test for them.

The 23rd human chromosome has two versions, the X and the Y.

Women have two X-chromosomes, while men have one X and one Y.

Y-DNA testing kits examine only the Y-chromosome, therefore only males can take this test. If you’re a woman who wants to test your father’s Y-DNA male line, you’ll need to test your father, uncle, brother, male cousin, etc. Basically any male on your direct paternal line. Testing the oldest generation possible is always best.

Because you can only get a Y-chromosome from your father, and he from his father, that means it tends to change very little over time.

How It Works

There are actually two sub-tests with Y-DNA testing.

The first is a short tandem repeat (STR) test. The STR test categorizes sections of the DNA according to how often a certain genetic pattern repeats.

The second is a single-nucleotide polymorphism (SNP) test. It works the same way as in autosomal DNA testing, but it only tests about 30,000 SNPs instead of 700,000.

What It Tells You

The STR test produces a summary of your haplotype. This can be compared to someone else’s results to determine how far back your most recent common ancestor might have lived.

An STR test is often used to determine how closely two people with the same surname are related, if at all.

The SNP test is more detailed, and among other things assigns you to a haplogroup.

A haplogroup is a group of people with one common ancestor and who lived in one or more specific regions.

Both Y-chromosome tests can help you locate relatives.

But like mtDNA, because the Y-chromosome changes slowly, you might be related many generations back. Although Y-DNA tests are much more useful for genealogy than mtDNA.

And because the Y-chromosome is only passed down through males, the test can only tell you about your direct paternal line.

The only company to offer individual Y-DNA testing kits is FamilyTreeDNA, which has three options depending on how detailed a test you want.

Y-DNA testing is especially useful for adoptees. It’s also a great ancestry test if you think you have jewish ancestry.

Living DNA and 23andMe bundles very basic Y-DNA testing with their autosomal DNA tests, but provide much less detailed results than FamilyTreeDNA.

Choosing the test that’s best for you

With three tests to choose from, how do you decide which is best for you?

It all depends on what you want to know.

Autosomal DNA

For most people, the autosomal DNA test is the clear winner, and it is the one test that every testing company offers.

Because your autosomal DNA comes from all of your ancestors, this test is good for finding a range of ancestors and living relatives.

It can also provide you with reasonable estimates of the ethnicity of your ancestors, or the regions of the world where they lived.

The main drawback to autosomal DNA is that it gets so jumbled together after a few generations that it becomes unreliable the further you try to go back.

Most of the time, an autosomal DNA test is only useful for about 6-8 generations.

Autosomal DNA can provide some great leads on finding others who are researching the same family tree as you.


Because mtDNA comes to you only from your mother, and from her mother, it only helps you trace one line.

You can use it to prove a common ancestor with someone else, but only in a direct maternal line.

It can, however, trace that line back a very long way – sometimes 10,000 years or more.

That can provide evidence that your mother’s maternal line came from a very specific region or ethnicity.

But it is less useful when finding living relatives.


The Y-DNA test is sort of like the mtDNA test, but it follows a direct paternal line instead.

That means a Y-DNA test can tell you about your father’s father’s father’s father, and many generations before that, but not about any of your other ancestors.

Y-DNA is most useful if you want to prove a connection to a certain ancestor.

Say that you have a common surname, like Smith, and want to know if you are related to someone else named Smith.

A Y-DNA can prove (or disprove) that the two of you are related.

Like the mtDNA test, Y-DNA may let you trace a line back for dozens of generations.

It can also tell you the ethnicity or region of origin of your paternal line.

One major drawback to a Y-DNA test is that only males have Y-DNA, so only males can take the test.

However, a woman can still find Y-DNA results by having a close male relative take it for her, such as her brother, father, paternal uncle, or cousin by a paternal uncle (but not her son, since he got his Y-chromosome from his paternal line, not hers).

In the same way, you can trace other paternal lines by asking an appropriate family member to take the test and share the results with you.

Ethnicity testing

All three of the DNA tests can provide you with information on where your ancestors lived.

But the information they provide varies from test to test.

  • Y-DNA and mtDNA tests will link you to very specific genetic lines, but keep in mind, they represent only a fraction of your family tree.
  • Autosomal DNA testing is what’s used for ethnicity testing of your entire family tree.

The companies that provide DNA testing divide the world up into regions in different ways. Each company has different ways of doing this.

That means that two different testing companies may give you different ethnicity estimates for the exact same DNA.

As more and more genetic data is collected, companies update their regions, too.

Some companies have had problems with their ethnicity estimates in the past. AncestryDNA, for example, used to be well-known for overestimating Scandinavian ancestry.

But the accuracy of estimates is constantly improving as more genetic data are collected, and there’s no clear indication that one company is more accurate than the others.

When a company does improve its ethnicity estimates, your profile will automatically be updated, too. You won’t have to retake the test to get the new results, but you will have to visit their site. Chances are they will not email you with the update.

Regions versus countries

It’s important to keep in mind that any DNA test will typically give a region of origin, not a country.

That’s because countries have changed many times throughout human history, and even within your lifetime!

Consider the case of Alsace-Lorraine, a 5,600 square mile region on the border of France and Germany.

Before the 17th century, the area was entirely Germanic (even though Germany as a country didn’t exist at the time).

During the 17th and 18th centuries, it was annexed by France.

In 1871, following the Franco-Prussian War, it was annexed by Germany.

Following World War I, it was returned to France.

So how can you say if your ancestors from that area were German or French using only DNA?

You can’t.

You can only say that your ancestors came from that region.

And because of all the migration and intermarrying across borders, the results you get aren’t going to be that specific, anyway.

Chances are they’ll bundle Germany and France together, and simply tell you those ancestors came from continental western Europe.

Native American ancestry

​Can DNA testing determine Native American ancestry?

Many people in the United States want to know if they have any Native American ancestry, and if so, from what tribes.

The good news is DNA testing can, in some cases, tell you if you have Native American ancestors.

Read our full guide to testing for Native American ancestry.

How to get started

If you’ve read this far, then chances are you are seriously considering having a genealogical DNA test done.

But I’m sure you still have a lot of questions, such as which DNA kit is best, how much it costs, how long it takes, and more.

You’ve got questions, we’ve got answers.

How is the DNA collected?

DNA is collected either with a cheek swab or a saliva sample, depending on which company you use.

For the most part, there’s no advantage to one method over the other. 

However, if the person being tested is very young (too young to be told to spit in the tube) or very old (and can’t produce enough saliva), the cheek swab might be easier.

Right now, the AncestryDNA and 23andMe DNA test kits use saliva samples; other companies use cheek swabs.

What happens next?

Once you’ve gathered your DNA sample, simply return it to the company for processing.

It will usually take six to ten weeks for your sample to be processed – but could take longer after the holidays since DNA tests are a popular gift.

Once your test is finished, you’ll be emailed with the test results.

Depending on the company and the test, your results may include:

  • your raw data
  • ethnicity estimates
  • lists of potential relatives

How much does it cost

Prices vary based on company and test.

Autosomal DNA tests by themselves usually run $69 to $99.

The only company to offer separate Y-DNA and mtDNA tests is Family Tree DNA. These tests will cost you a few hundred dollars, depending on the number of markers tested.

As mentioned above, LivingDNA and 23andMe bundle in basic Y-DNA and mtDNA tests. But they only test a limited number of markers, and do not provide any matching. They really only give you haplogroup information.

23andMe offers a combined genealogy and health report for a single fee.

Health reports can identify your carrier status for a few dozen different diseases or conditions, which could signal future health risks for you or your children.​

In addition to the cost of the test, most companies also charge $10 to $12 for shipping.

See the table at the top of this page for a full comparison.

Buy it as a gift

You can also buy any of these DNA testing kits as a gift for other family members.

This is a good way to increase accuracy by comparing test results.

It also lets women use the Y-DNA test by having a male relative take it for them.

Which test is best for you?

It depends on your goals…

Is it worth it?

So is genealogical DNA testing right for you?

In the end, is it really worth the cost and bother?


Even if genealogy is only an occasional hobby for you, these tests can provide you with some very enlightening insights into your family history.

And for the serious genealogist, it is getting to the point where they are nearly essential.

Genealogical DNA testing is finally accurate enough, inexpensive enough, and useful enough for connecting with your family. I recommend it to everyone interested in learning more about their roots.

I know that this article is old, but I have been interested in my ethnicity. I have a good idea of what ethnicity I am, but I like many people want a thorough DNA test. Now, it seems like Ancestry is the closest to what I am looking for. The only issue that I have with ALL of these DNA tests is privacy. I don’t like that they have the authority to keep my information for their own purpose. This is the reason why I won’t take any of these DNA tests, and as curious as I am, I want… Read more »

Hi Mark, Thank you for such an informative and clearly stated article. I am American Jewish and have done several of the tests. I’m now submitting a question for a close friend. He is Burmese and would very much like to test. His biggest interest is ancestral origins. Would he be best off doing a Ydna test or could he find sufficient information in an autosomal test? I assume the Y test would be with Familytree. If so, should he also do an autosomal test with Familytree, or with Ancestry or MyHeritage? Thank you so much!


So you probably have answered this already and I have no idea. I’m just trying to dumb it down for myself. Really great info not overloaded with the information. I’m trying to do a ancestor tree. I have the names all the way back to 1900 on my dads and moms direct line. I was wandering what test would be best to take to find out more exact answers on bloodline and names in my family all the way back to 1700-2000?


Thank you for your reviews
I’ve been looking at CRI Geneticsfor family tree but especially for health reasons …I notice you did not even mention them…. is there a reason for that?


I also am interested in CRI Genetics; anyone used them?


I used them, and while I did not use it for health reasons, I found their test a little more believable concerning ethnicity than Ancestry. Crigenetic said I had no Korean and am Japanese with European (white) ancestry, and Ancestry stated I did have Korean and no Japanese or European, but I was born with red hair and am constantly mistaken for Japanese. I don’t know how to feel about the results.


I was born in flight from the Middle East to the USA back in 2008, and the little I know is that my mom’s family were either Jew or Muslim.

Which test would be best to separate all types of Jew branches and Muslim branches???

Seeing that I am fair olive skin tone, I am very sure that my mom’s family was more than just one or the other.

Alberto F. Trevino

I had my test taken by National Geographic years ago when they initially started. Do you know if they have updated the tests or technology, science etc.


Awesome info! Much appreciated


I’ve been reading the Q&A portion and didn’t find you suggesting 23&me. My father used 23&me and I want to purchase. Kit for my daughter’s bday…. should I stick with the same company?

Also, is it only 23&me that offers the health testing? How accurate has it been?

Hi Mark, can you tell me which test my mother in law would need to take, for me to find genealogical information on her paternal line? She never knew who her birth father was apart from the fact that he was an American serviceman stationed in England after WW1. She has no siblings. Is there a test suited for this? As she is nearing 100 years old, it would need to be a cheek swab test. Would it be beneficial to have my husband tested instead? Thanks.

S. Alpa

Hey, I don’t know my dad, all I know is he’s probably Indian, from Kashmir, my grandmother passed away and I have her ashes (I never knew her either) I would like to know where my grandmother / father is from so I can take her back to scatter her ashes where she belongs..
My mum can also take a DNA so we can separate what’s her and what’s me but which test would show me where in India please?


One factor I would like to see in the review is the time taken to receive your results. I have been waiting 22 weeks for results from livingdna. Is this typical? I’ve emailed them and just been given a stock answer.


I’ve a taken a DNA test with the main purpose of tracing my father’s lineage but then I read that cos I’m female it is not possible. I don’t have any living male relatives on my father’s side. Does this mean my results are only from my mother’s lineage?

Camille Devaux

It makes sense that you would want to find a good service for your ancestry charts. This is a great way to make sure that you are getting the right results. I like the idea that you can find a service that will narrow the searches and will search for something like that.

Michael J Hayde

Hi. There doesn’t seem to be a way to search comments, so I apologize if this has been brought up. Every so often, I get ads from Genealogy Bank for the GPS ORIGINS DNA Test, which claims to “pinpoint your ancestry even to the town or city.” Have you had a chance to rate this product against the others? If so, how does it measure up?

Sports Performance

I would like to learn more about my genetics but have no interest in connecting with “long lost” family members. I also don’t want my personal info plastered about for privacy reasons. Which service(s) offer the best for what I am looking for that will also respect my need for privacy?


Hi. My name is Felicia. I am 53. I want to start looking for my mother. I feel that I am ready. My parents were married in Seoul, Korea in 1963. He is American. She is Korean. They moved to Los Angeles, CA, and I was born in 1965. They separated and divorced in about 1968. He got custody of me (rare for a man at that time), and he moved us to NJ. He passed away when I was 27, and I have their marriage certificate, so I know her parent’s names and the village they are from. I… Read more »

My Dad was adopted, and I believe I found his birth sister. Which DNA test do you believe is the best to confirm if this woman is indeed my aunt or not?

Michael Beavis

Trying this again. Not sure why it is not staying up. My Dad was adopted, and I believe I have found his birth mother however, she has passed away. I did find her daughter, and to confirm if she is indeed my aunt, which DNA test do your suggest?


I was adopted from guatemala and I was wondering which test would be better to potentially find family members?

Steve Allen

Hi, i have never known my dad who was a greek Cypriot who as far as i know returned to Cyprus in the war of 74, he had some brothers and a sister over here, i was just wondering if you could advise on which company would be best?i was thinking of ancestry as it sounds like they have the biggest database, your advice much appreciated-steve


Ann Boleyn was my direct ancestor (15 generations)’s aunt on my fathers side, according to My Heritage. What DNA test would be best for me to discover ancestors on my fathers side of the family? I am a male.

joy sun

I wish I could afford these.


I am looking for health and maybe father as I do not know who he is. My birth certificate has my mothers ex husband as the father so I would have the same last name but he is not my father. I have very little if any information on him.
I have had some health issues that do not follow my mothers side so I am looking for that information to as it will give me some insight as to if they are from his side. Also my mother has passed.
What test is the best for my use.


Hello! Which test would you recommend, I’m trying to find more of my ancestors but would also like to find out what is my ethnic background. I already found most of my relatives up to 4-5 generations (1750), but would like to connect as much as possible

I was lucky enoguh that 3 of my cousins already connected a large portion of our family tree, so I currently have around 6120 blood relatives.


Hi, I was wondering if it would be worth it for me to take an ancestry test. Both of my parents are from mainland China, and I know that my grandparents are full Chinese, however their families came from different provinces. Are any of these tests accurate enough that I can figure out which provinces or at least areas of China they came from?


Hi I am hoping to find help. i took 23 and me with my half brother and half sister and i did not connect to either of them but they connected to each other. I also came up as 38% Jewish but my mom and dad are Italian! my Mom swears there is a mistake. my parents were never married so i grew up without him for most of my young yrs. i look like his twin and both half sister and brothers twin as well. i do not have a match closer then 4-6 generation on what they say… Read more »


I am adopted and have no idea of health history and would like to give my kids some idea of what they have to look forward to. I would of course like to learn which culture I am most like so what do you suggest?

jackie kutsin

My Mom and Dad were both adopted as babies. They were very happy with My Great-Grandparents and never felt the need to find out what Nationality they really were. That was in the early 1900’s. I would really like to know what ethnic background I am even though I am much older now. Have always wanted to know am I French? Irish? Both?. Any advice? Not specifically looking to go back 6 generations. Just a few to give me some idea. Thanks


Hi. I’ve tested myself on Ancestry, 23andMe, and Nat Geo. The first two gave almost the same results, but Nat Geo was pretty different. I know they use different testing methods, so I was wondering which is more accurate? Also, I’m a woman, and I know I’d get a fuller picture if my father were tested. Which of those companies does Y DNA tests that can be linked to my results? Thank you so much fo this article! It’s very thorough and informative!


Hi Mark!

I read through the article but being a total newcomer to the concept of this sort of DNA testing I wanted to ask your opinion.

I’m very curious to dig as far back into my ancestry as I can. I’d love to find out where my ancestors of 1000-2000 years ago might have been from, if that’s at all possible. Is there a test you’d recommend for that?

Thanks very much for the great article!


Hi, great article! I am interested in obtaining a detailed ethnicity breakdown and analysis. Which service(s) would be best for this? Thanks!


Hello, I’m adopted. I know my maternal biological side, not sure on paternal. If I take a DNA sample from ancestry is it possible I may find the paternal side by my DNA? I have a sibling, his father possibly could be mine as well, or I have another name, but have no idea where he is or any possible relative. We have an ancestry family tree, in which I am under my bio mom and the father of my sibling( who is on my birth certificate). Is it possible to find relatives on paternal side?

I think you have a very good chance of finding your paternal side on either 23andme or ancestry. We found a new cousin (my uncle was her father when he was a very young man) and my friend found his half sister he never knew existed. Wait for a sale and submit your dna to both then you can always upload your raw dna to gedmatch and myheritage for a bigger pool of matches. Good luck.


Thanks a lot for this great article. I have 2 questions:

1- In my mothers family, all of them had heart attack unfortunately, Is there any dna test that tells me that I will suffer this too in future?

2- Which package is the most complete one (for example let me know if I need to take multiple tests)


I ‘ve done MyHeritage to find my origin etc but I would like to transfer my DNA results to other databases of other companies as well ( Ancestry, 23andme, FamilyTree etc) so if one of my relatives uses the DNA test of another company to get to know about our relationship. I know this is possible, but I don’t know how. Do you know to whom I should address for this?
Thank you.

HI, which is the best DNA test to find my Greek ancestors? I have done the My Heritage one, but does not show Greek, but Balkans and Scandinavia, and some others too. Is there a test that could narrow my search down?

Very informative And interesting.

Hi, I am wanting to be tested to see that my birth father is who I am told it is. He is deceased, he does have a couple sisters and a few nephew’s. I am female, so is it possible to have someone tested to make sure who my real father is???


Or if that is all your are interested in then go to a local place that is specialising in just that. There are dna testing places all over the US to test for parental proof.

Hi.. My great grandfather’s wife. Family oral history has her with “some” Native American heritage. I took Ancestry DNA test and apparently the percentage Native American is too low to show up at their test, or Family Oral History is incorrect. What test is best for me to take to register Native American ancestry in my case? Thanks ~ Wayne O


You don’t need an ancestry subscription to use the family tree functionality as stated in your article – you need the subscription to view the records in their database. If you cancel your sub you can still view and alter your family tree.

Hey Mark, I noticed that you wrongly claim that 23andMe does not examine your mtDNA and yDNA, which is one of their main advantages.
Sorry but it seems that something is smelly here with your review – you cannot make such a mistake; it s too obvious dude..

Hey Mark, what would you recommend to find relatives for a Portuguese family?
I know my relatives are Portuguese until the 4th generation but have no clue for the rest.
I know ancestry has the biggest database, but MyHeritage has a good international database.
Which one do you recommend?
thank you!


Update on 23&Me, their database has now reach 10 Million.

Hi Mark, there’s some evidence that my mother’s family were Gypsies. Is it possible that DNA from these Roma/Gypsy ancestors would show up in anything other than mtDNA because Gypsies are a “founder population”?

Janet Dixon

Hi there, interesting info – thanks. You missed out on a very important point though, 23&Me also checks for Neanderthal pointers, which other sites do not appear to do… cheers

I want to know if my older brother is related to me. I now have ordered two(2) DNA kits for he and I to take. I am interested to find out if he is related. How do I go about asking this specific question to 23 & M


I would love to know how my grandparents ended in the regions they did, and would love to trace back to overseas family

I think you should add “privacy policy” to your criteria. These are increasingly a concern to people, and they, in conjunction with the provider’s “Terms of Service” are as, or more, difficult to understand than the various types of DNA testing!

I don’t see CRI Genetics included in this list. Is there a reason for that? How does that company compare?

I was adopted with no living adopted parents. I know my maternal lineage. I do not know my father’s name, only that he was an American Serviceman. If I take a y-111 test, will names of relatives, be reported in the results?


Hi, I’m fairly new to genealogy but my main concern is do you get names, l know the last name we’ve been using as our family name for the last four or five generations isn’t correct and would love to find out who we really are, is that possible?, and on my mother’s side the family is basically instinct, mostly females and no family name, surely there are relatives living, we don’t know them, will we be able to know who they are?
