Submit a Surname
Know of a surname tied to a documented Y-DNA haplogroup, whether from a published study or your own family research? Add it to our free database.
Two kinds of submissions are welcome: a peer-reviewed academic study linking a surname to a haplogroup (these get added with full confidence ratings), or your own family's documented result (personal test, family record, an independent researcher's write-up). The second kind gets added too, but clearly tagged "⚠️ Unverified, not peer-reviewed" so visitors always know the difference.
