2 small sub-branches more without a page: 35 kits. On the branch itself, without a resolved sub-branch: 3,433 kits.

Surnames #

Surnames that testers entered at FTDNA, over the whole branch with its sub-branches: 1,808 distinct among 14,169 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-L21: 3,239 samples. The common ancestor lived 4,500 years ago (4,200–4,800); the branch split off 4,500 years ago (4,200–4,800).
