Surnames #

Surnames that testers entered at FTDNA, over the whole branch with its sub-branches: 3,920 distinct among 34,597 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-L51: 9,559 samples. The common ancestor lived 5,700 years ago (5,100–6,400); the branch split off 6,100 years ago (5,500–6,800).
