Haplogroup N-M231
N-M231 is the lineage of the Eurasian north — spread from Siberia with Uralic-speaking peoples, it is today the leading paternal line in Finland, the Baltics and northern Russia.

Origin and distribution of N-M231
N-M231 tells a west-moving story most European haplogroups tell in reverse. Born in East Asia and carried north and west through Siberia, its N1a1 (N-M46/Tat) branch expanded across the whole Eurasian taiga belt within roughly the last four thousand years — arriving in the eastern Baltic in the Bronze–Iron Age transition, where ancient DNA marks its appearance alongside the ancestors of today's Finnic and Baltic peoples.
Today N is the most common paternal lineage in Finland (particularly the east), Estonia, Latvia and Lithuania, among the Sámi, and across northern Russia's Uralic-speaking peoples — Komi, Udmurts, Nenets — as well as the Yakuts of eastern Siberia, where a founder effect made it nearly universal. Its correlation with the Uralic language family is one of the most cited gene–language parallels in population genetics, though Lithuanians and Latvians show the same lineage with Baltic speech.
One line among many: your Y haplogroup traces a single paternal line — one ancestor per generation out of thousands — so it is a thread of deep ancestry, not an ethnicity and not a percentage of who you are. Two men in the same branch share a forefather, but the rest of their genomes can differ as much as any two strangers'.
Frequently asked questions
What is haplogroup N-M231?
N-M231 is the lineage of the Eurasian north — spread from Siberia with Uralic-speaking peoples, it is today the leading paternal line in Finland, the Baltics and northern Russia. It is a branch of the Y-DNA tree: everyone in it inherits the same set of defining mutations from one shared forefather.
How do I find out if I belong to N-M231?
If you have already tested with a consumer DNA company, the free Y-DNA Clade Finder reads a raw DNA export (23andMe, AncestryDNA, MyHeritage or a VCF) and places you on the tree at the resolution your file supports — free, and the file is discarded after analysis. A dedicated Y-DNA sequencing test resolves deeper branches than a genotyping chip can.
Does belonging to N-M231 make me descend from one people?
No. A haplogroup follows a single paternal line — one ancestor per generation — while the rest of your ancestry doubles every generation back. It is a deep-time thread, not an ethnicity, and two members of the same branch can otherwise be as genetically different as any two strangers.
What does this page's tree data show?
The live browser below shows the branch inside the full Y-DNA haplotree of tested lineages — its sub-branches, the variants that define them, and the countries its testers report. Counts reflect people who have taken a Y-DNA test and shared an origin, so they describe the tested world, not ancient frequencies.
