YFull

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.

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.

R-Z3023
1,744 · 87.5% 2,200 years

2 small sub-branches more without a page: 18 kits. On the branch itself, without a resolved sub-branch: 232 kits.

Surnames #

Surnames that testers entered at FTDNA, over the whole branch with its sub-branches: 145 distinct among 617 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%.

R-A114: 103 samples. The common ancestor lived 3,500 years ago (2,800–4,300); the branch split off 3,500 years ago (2,800–4,300).
