From YFull samples that gave a mother tongue: the part of a people's samples that falls into this branch. Peoples with at least 3 samples in the branch are listed.

Sub-branches #

Sub-branches that have their own page (50 kits or more). The bar is the kits in the sub-branch with its own sub-branches; the age is when its common ancestor lived.

Surnames #

Surnames that testers entered at FTDNA, over the whole branch with its sub-branches: 169 distinct among 693 kits. FTDNA gives surnames per branch only, with no country attached, so they cannot be split by country.

YFull

The same branch on YFull #

YFull builds its tree from the same SNPs; the node is matched by name or by a shared SNP. TMRCA is when the common ancestor of all samples lived, formed is when the branch split from its parent. Intervals are 95%.

I-Z141: 603 samples. The common ancestor lived 4,000 years ago (3,400–4,600); the branch split off 4,000 years ago (3,400–4,600).
