For German ancestry research, two autosomal tests rise above the rest: AncestryDNA and MyHeritage. Both estimate your ethnic origins and match you with genetic cousins, but they have very different strengths, and the right choice depends on whether your research leans toward the American or the European side of the Atlantic. Here is how they compare where it matters for German roots.
Database size and where the testers are
AncestryDNA has the larger database by a wide margin — over twenty million testers against MyHeritage’s roughly six million. For cousin-matching, more testers usually means more matches, and AncestryDNA’s dominance in the United States means most of your American German-descended cousins are there. But raw size is not the whole story for German research: MyHeritage is far stronger in Europe, and German and other European users frequently report more relevant matches from their ancestral countries on MyHeritage than on Ancestry. If your living cousins are mostly in the US, Ancestry wins on numbers; if you hope to match people in or recently from Germany, MyHeritage often does better.
Ethnicity estimates
Both break out a “Germanic Europe” component and divide the world into hundreds of regions, and both refine their estimates over time. MyHeritage is known for detailed European breakdowns; AncestryDNA updates frequently and offers a “by parent” split that separates your estimate into maternal and paternal sides. As always, treat the percentages as approximations — neither can pinpoint a German region precisely, because German DNA overlaps with that of its neighbours.
Features that matter for genealogy
- AncestryDNA: ThruLines suggests how you connect to matches through shared ancestors, and the platform ties into an enormous collection of (mostly US) historical records — though viewing match trees needs a subscription.
- MyHeritage: AutoClusters groups your matches into likely shared-ancestor clusters, and a chromosome browser lets you compare exact shared segments — a tool serious genetic genealogists value and one Ancestry does not offer.
The upload advantage
This single difference often settles the decision. MyHeritage accepts free uploads of raw DNA data from other companies; AncestryDNA accepts none. That means you can test with AncestryDNA — getting into the largest database — and then upload your raw data to MyHeritage for free to gain its European matches too. You cannot do the reverse. For German research, this makes “test at Ancestry, upload to MyHeritage” a genuinely powerful one-test strategy.
Price and records
MyHeritage is usually the cheaper kit and frequently discounted, which makes it an easy budget pick or second test. On records, the two specialise differently: AncestryDNA pairs with deep US collections, while MyHeritage’s SuperSearch is stronger on European records — again favouring MyHeritage for the German side of a tree.
So which should you choose?
- Researching mostly US-based German-American cousins, or want the biggest pool: start with AncestryDNA.
- Focused on European or Germany-based matches, on a budget, or want a chromosome browser: choose MyHeritage.
- Want the best of both for the least money: test with AncestryDNA, then upload your raw data free to MyHeritage.
Whichever you pick, the matches are only the start — the real work is contacting cousins and tying them into your tree, covered in How to Find German Relatives with DNA. And if a specific paternal surname is your puzzle, neither autosomal test beats FamilyTreeDNA’s Y-DNA for that job.
Records and trees behind the DNA
Both companies are more than DNA databases — each sits on a records platform, and they specialise differently. AncestryDNA is backed by the largest collection of US historical records anywhere, which is invaluable for tracing your German immigrant ancestor’s American life and identifying when they naturalised. MyHeritage’s SuperSearch is comparatively stronger on European records and has absorbed numerous European collections, which helps on the German side of the tree. For German research you often want both perspectives: Ancestry to document the American chapter, MyHeritage for the European one.
A worked scenario
Imagine you are descended from a Pomeranian couple who emigrated in the 1880s and settled in Wisconsin. On AncestryDNA you find dozens of American cousins descended from the same couple, and ThruLines proposes how you connect — great for confirming the US branches. But none of them know the village. You upload your raw data free to MyHeritage, and there a match in northern Germany appears, with a tree naming the parish. The two databases did different jobs: Ancestry mapped the diaspora, MyHeritage reached back toward the homeland. Neither alone would have finished the job.
Which has better German region detail?
Both place you in “Germanic Europe” and subdivide Europe into many regions, and both refine over time. MyHeritage is often praised for granular European breakdowns, while AncestryDNA’s frequent updates and its “by parent” feature — which splits your estimate into maternal and paternal halves — can help you work out which side your German ancestry sits on. Neither, though, can resolve your ancestry to a German region precisely enough to replace records.
Frequently asked questions
If I can only afford one test, which is better for German ancestry?
Choose AncestryDNA if your cousins are mostly American and you want the biggest pool; choose MyHeritage if you want European matches, a chromosome browser, and a lower price. Remember you can test with Ancestry and then upload to MyHeritage free.
Can I move my AncestryDNA results to MyHeritage?
Yes — download your raw DNA file from AncestryDNA and upload it to MyHeritage at no cost to gain its matches. The reverse is not possible, which is why testing at Ancestry first is often the smart order.
Accuracy, updates, and the long game
Neither company is meaningfully “more accurate” than the other for German ancestry — they use different reference panels and algorithms, which is why the same DNA yields somewhat different numbers at each. What matters more over time is that both refine their estimates and matching as their databases grow, and these updates arrive automatically and free. So the test you take today will quietly improve, and a match who has not yet tested may appear next year. Treat your results as a living resource you revisit, not a one-time verdict, and check back periodically for new close matches on whichever platform you use.
Do my results change over time?
Yes — ethnicity estimates are recalculated as reference panels expand, and your match list grows as new people test. Both happen automatically at no cost, so it is worth logging in every few months to see new matches and refined estimates.

A note on privacy: a DNA test shares your genetic data with a company, so review each provider’s current privacy policy before testing — who can see your data, whether you can delete it, and the rules on law-enforcement access. Policies and company ownership can change. Pricing and database figures in this article are approximate and current as of 2026.
