Surnames #

Surnames that testers entered at FTDNA, over the whole branch with its sub-branches: 1,186 distinct among 6,040 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%.

I1: 4,212 samples. YFull publishes no age for this branch.
