For most people with Polish roots, the best DNA test is MyHeritage DNA. It reads your whole genome, it reaches relatives in Poland and the rest of Europe better than the US-centered companies, and it gives men their paternal Y-DNA haplogroup at no extra cost. This guide explains why it’s our first pick, when another test is the better tool, and how to turn your results into real Polish ancestors.
DNA won’t name your ancestral village and it won’t qualify you for Polish citizenship. What it can do is confirm that a family story is true, find the cousin who has the old letters, and break through when parish books were burned. It works best alongside the records research covered in our guide to tracing Polish ancestry.

Our pick
The best DNA test for Polish ancestry
MyHeritage DNA reads your whole genome, reaches relatives in Poland and across Europe, and gives men a free Y-DNA haplogroup.
The Three Types of DNA Test (and Which Polish Question Each Answers)
Before you pick a company, pick a test type. The three types follow different lines of your family, so they answer different questions.
| Test | Who can take it | Which ancestors it covers | Best Polish use | Where to test |
|---|---|---|---|---|
| Autosomal | Anyone | All lines, on both sides, going back about five to six generations | Finding cousins, confirming relationships, ethnicity estimates | MyHeritage, AncestryDNA, 23andMe, FamilyTreeDNA |
| Y-DNA | Men only | Father’s father’s father’s line only | Testing whether two families with the same surname share a common ancestor | FamilyTreeDNA; basic haplogroup free at MyHeritage |
| mtDNA | Anyone | Mother’s mother’s mother’s line only | Ruling a suspected maternal-line connection in or out | FamilyTreeDNA |
Autosomal DNA: the test almost everyone should start with
You inherit autosomal DNA from all your ancestors. That’s why it finds cousins on every branch, from your Polish grandmother’s side as well as your Irish grandfather’s. It is also what all the big companies sell as their standard kit. The catch is that it fades with distance. Close cousins share a lot of DNA, but by about the fifth generation back, some of your ancestors left you no detectable DNA at all. For immigrant families who arrived between the 1880s and the 1920s, though, that range reaches back to the generation that left Poland, which is usually the one you’re trying to find.
Y-DNA: useful for surnames, with one Polish catch
A man’s Y chromosome passes from father to son almost unchanged, much like a surname. A Y-DNA test can therefore show whether two Nowak families from neighboring parishes share one founder or are unrelated. The catch is that the broad result tells most Polish men very little. Studies put haplogroup R1a at somewhere around 55–60% of Polish men, so “you are R1a” doesn’t narrow anything down. MyHeritage’s free haplogroup is a good first look. To settle a surname question, though, you need marker matching (Y-37 and up) or the deep Big Y-700 test at FamilyTreeDNA. Before you read too much into a surname match, check our notes on how Polish surnames changed after emigration.
mtDNA: the narrowest of the three
Mitochondrial DNA follows only your direct maternal line. The surname on that line changes every generation, and mtDNA mutates slowly, so exact mtDNA matches can share an ancestor many centuries back. It’s worth taking when you need to settle a specific maternal-line question, for example whether two women in an 1890s Galician record were sisters. It’s a poor first test.
The Best DNA Tests for Polish Ancestry, Ranked
The database sizes below come from genetic genealogist Leah Larkin’s March 2026 count at The DNA Geek. Prices change constantly and every company runs frequent sales, so check the current price before you buy.
1. MyHeritage DNA: Best Overall for Polish Ancestry
- Whole genome sequencing: Since October 2025, new kits read close to your entire genome (about 3 billion base pairs) instead of the roughly 700,000 markers a standard chip reads. MyHeritage is the first major consumer company to make this switch, and it did so without raising the price.
- European reach: About 9.6 million kits, with a stronger share of European and Israeli testers than the US-centered companies. The site is also available in Polish, which makes it easier for relatives in Poland to test and reply.
- Free Y-DNA haplogroup: Since August 2026, men get their paternal haplogroup from the same kit, with no second test needed.
- Detailed origins: Its Genetic Groups feature breaks your ethnicity across more than 2,100 regions.
- Real research tools: A chromosome browser and shared segment data, which Ancestry doesn’t offer.
Good to know: MyHeritage stopped accepting DNA uploads from other companies in August 2025. If you tested elsewhere, you need a MyHeritage kit to appear in its matches.

Find your Polish relatives with MyHeritage DNA
MyHeritage no longer accepts DNA uploads, so the only way to reach its European matches is to test with its own kit.
2. FamilyTreeDNA: Best for One Specific Line
FamilyTreeDNA has the largest Y-DNA and mtDNA databases in consumer genealogy, plus just under 1.8 million autosomal (Family Finder) kits. It hosts volunteer-run projects such as the Polish Project, where testers compare paternal and maternal lines from the old Commonwealth lands. It also accepts autosomal DNA files from other companies, so you can add your MyHeritage results and get extra matches without buying another kit. Choose it when you have a surname or direct maternal-line question to settle.
3. AncestryDNA: The Biggest Database, Strongest in North America
AncestryDNA has the largest database, close to 30 million kits, most of them in the US. Its late-2025 update added Polish regions such as Southern Poland and Northeastern Poland. It has no chromosome browser, it doesn’t accept files from other companies, and it doesn’t offer Y-DNA or mtDNA results. It’s a good second test if your family settled in North America and you want to widen your cousin search there.
4. 23andMe: Only if You Want Health Reports
23andMe has a little under 14 million kits, with about 11 million customers opted in to relative matching. It went bankrupt in 2025 and was sold in July 2025 to TTAM Research Institute, a nonprofit led by co-founder Anne Wojcicki. It added 32 Polish Genetic Groups in 2025. For genealogy alone, the tests above serve Polish researchers better.
5. LivingDNA: Not Recommended for Polish Research
LivingDNA still sells kits, but its matching database is small and concentrated in the UK. Every option above will find you more Polish relatives.

Which Test Should You Take? Start From Your Question
“I want to find relatives still living in Poland.”
Take MyHeritage DNA. Its user base leans more European than its US competitors’, and the site is available in Polish. Few people in Poland test at all, so expect a handful of matches, not hundreds. Each one can be a direct line to a parish or a village.
“My grandparents came from Poland and I want to find cousins.”
Start with MyHeritage DNA to cover both sides of the ocean. Then upload your raw data to FamilyTreeDNA and GEDmatch for free extra matches. If you can afford a second kit, AncestryDNA adds more North American cousins.
“Are these two families with my surname related?”
Have a man from each direct paternal line take a FamilyTreeDNA Y-DNA test (Y-37 at minimum), and join the Polish Project. If both men match closely, the lines connect. If they don’t, the shared surname is a coincidence, which is common with names like Nowak or Kowalski.
“My family was Polish-Jewish.”
Test at MyHeritage DNA. It has a strong Jewish and Israeli user base. Be ready for endogamy: generations of marriage within one community make distant cousins look closer than they are. Read our Polish-Jewish genealogy guide and pair DNA with JRI-Poland records.
“I’m adopted, or one of my parents is unknown.”
Cast the widest net you can. Test at MyHeritage and AncestryDNA, then upload your raw data to FamilyTreeDNA and GEDmatch. With an unknown parent, every additional database improves your odds.
Test the oldest generation first
If a parent, grandparent, or great-aunt is still living, test them before (or as well as) yourself. Your grandmother carries roughly twice as much of the immigrant generation’s DNA as you do. Her matches reach one generation further back, and you can tell at a glance which side of the family a match belongs to. Once that generation is gone, their DNA can’t be collected again.
Reading Your Ethnicity Estimate
Many people with four Polish grandparents get results that show far less than 100% “Polish”. Others are surprised by large Baltic, Ukrainian, German, or Balkan percentages. There are three reasons, and none of them means the family story is wrong:
- Poland’s borders moved. Between the partitions and 1945, the country was redrawn repeatedly. German, Lithuanian, Ukrainian, Belarusian, and Jewish communities lived alongside Poles for centuries. Your DNA reflects those populations, not a modern border. Our guide to the three partitions explains who ruled where.
- Estimates describe the distant past. They compare your DNA with reference populations that reflect ancestry several hundred years back, not where your great-grandparents were born.
- Each company draws different lines. The same person can show “East European” at one company and “Southern Poland” at another, and the labels change with each update.
Read your ethnicity estimate as background. Your matches are where the real genealogy happens.
After Your Results Arrive: Five Steps That Actually Find Ancestors
1. Download your raw data and spread it around
Download your raw DNA file from your testing company. Upload it to FamilyTreeDNA (Family Finder transfer) and GEDmatch, which both accept files from other companies, and you’ll appear in their databases without buying another kit.
2. Filter matches by Polish places and surnames
Search your match list for the birthplace “Poland” and for your family surnames, including old spellings. A match whose tree shows a Galician village 20 km from yours is worth far more than a closer match with no tree.
3. Group your matches into clusters
Use the “shared matches” tool to sort cousins into groups. Each cluster usually points to one ancestral couple. Once you know which cluster is your Polish great-grandparents, every new match in it is a lead. MyHeritage’s chromosome browser shows exactly which segments you share, and the free tool DNA Painter lets you map which piece of which chromosome came from which ancestor.
4. Message matches the right way
Keep the first message short and specific. For example: “Hi, we share 85 cM. My great-grandparents Jan Wiśniewski and Maria Kozieł came from near Tarnów around 1905. Do any of those names or places appear in your family?” A first message that names surnames and places gets far more replies than a vague “how are we related?”
5. Take every lead back to the records
DNA tells you that two people are related. Records tell you how. When a match points to a parish, search it in Geneteka and find the scanned books through Metryki to confirm the connection on paper. A MyHeritage free trial also lets you search its historical records and build your tree next to your DNA matches.
Privacy: decide before you test
- Every company lets you opt out of relative matching and of research use. Check those settings as soon as your account is open.
- MyHeritage says it doesn’t sell or license DNA data to third parties and prohibits law enforcement use.
- GEDmatch lets each user choose whether law enforcement matching applies to their kit. Read the options during upload.
- Testing a relative means sharing their DNA, too. Get their consent, and agree in advance who manages the kit.
What DNA Can’t Do for Polish Research
- It can’t prove Polish citizenship. Citizenship by descent is confirmed with birth, marriage, and citizenship documents. See the documents you need and whether you’re eligible.
- It can’t name your village. Matches can point toward a region, but the village comes from records. Use our guide to finding your ancestral village.
- It can’t replace the parish books. For most Polish families, metrical records reach further back than DNA can usefully go.

Frequently Asked Questions
What is the best DNA test for Polish ancestry?
MyHeritage DNA is the best all-round choice. It uses whole genome sequencing, reaches relatives in Poland and across Europe, and gives men a free Y-DNA haplogroup. For a deep surname question, add a FamilyTreeDNA Y-DNA test.
Which DNA test is most accurate for Polish ethnicity?
No company is “most accurate” for every Polish family. MyHeritage reads your whole genome and breaks results into more than 2,100 Genetic Groups, and its competitors have also added Polish regions in recent updates. Ethnicity percentages still vary between companies and between updates, so use them as background, not proof.
Can a DNA test prove eligibility for Polish citizenship?
No. Polish citizenship by descent is confirmed with civil and church records proving descent from a Polish citizen. DNA results aren’t part of that application.
Can I upload my DNA results from another company to MyHeritage?
No. MyHeritage stopped accepting DNA uploads in August 2025, so you need a MyHeritage kit to get its matches. You can still upload raw data from other companies to FamilyTreeDNA and GEDmatch.
Will a Y-DNA test tell me where my Polish surname comes from?
Not on its own. It tells you which men share your direct paternal line. If several of them carry your surname and trace back to the same area, that is strong evidence of a common origin. The broad haplogroup alone, usually R1a for Polish men, is too common to pinpoint anything.
Should I test with more than one company?
It helps, because your cousins are spread across different databases. Start with MyHeritage DNA, upload your raw data to FamilyTreeDNA and GEDmatch for free, and add a second kit later if you want to widen the search.
