Most common among these peoples #
From YFull samples that gave a mother tongue: the part of a people's samples that falls into this branch. Peoples with at least 3 samples in the branch are listed.
- Serbs: 1.8% of samples (8 of 445)
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.
1 small sub-branch more without a page: 41 kits. On the branch itself, without a resolved sub-branch: 155 kits.
Surnames #
Surnames that testers entered at FTDNA, over the whole branch with its sub-branches: 24 distinct among 72 kits. FTDNA gives surnames per branch only, with no country attached, so they cannot be split by country.
