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.
5 small sub-branches more without a page: 45 kits. On the branch itself, without a resolved sub-branch: 196 kits.
Surnames #
Surnames that testers entered at FTDNA, over the whole branch with its sub-branches: 609 distinct among 3,035 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%.
R-Z2976: 664 samples. The common ancestor lived 4,100 years ago (3,800–4,300); the branch split off 4,100 years ago (3,800–4,300).
