R-Z8

Equivalent branches, the same kits: R-Z5 (3,349 kits, 3,400 years)

R-Z8 is a branch of the FamilyTreeDNA Y tree with 3,349 kits that gave a country, counting all sub-branches. It is most common in these samples: Belgium (Flanders) (6.1% of kits), Netherlands (4.7% of kits), Barbados (4.7% of kits). The branch's common ancestor lived about 3,000 years ago: the FTDNA Discover estimate runs from 2,600 to 3,400 years ago. The oldest of the equivalent branches, R-Z5, split off about 3,400 years ago by Discover. YFull has 326 samples in this branch and dates its common ancestor to 2,900 years ago.

Surnames #

Surnames that testers entered at FTDNA, over the whole branch with its sub-branches: 230 distinct among 954 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-Z8: 326 samples. The common ancestor lived 2,900 years ago (2,600–3,400); the branch split off 3,700 years ago (3,200–4,300).
