Most common among these peoples #
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.
- English: 0.4% of samples (4 of 1,050)
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.
2 small sub-branches more without a page: 7 kits. On the branch itself, without a resolved sub-branch: 3 kits.
Surnames #
Surnames that testers entered at FTDNA, over the whole branch with its sub-branches: 5 distinct among 76 kits. FTDNA gives surnames per branch only, with no country attached, so they cannot be split by country.

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%.
J-ZS4199: 20 samples. YFull publishes no age for this branch.
