FTDNA Y-tree branch

I-M423

I-M423 is a branch of the FamilyTreeDNA Y tree with 3,791 kits that gave a country, counting all sub-branches. Almost all of its kits sit in a single sub-branch, I-CTS5375, so this branch gets no conclusions of its own. It is most common in these samples: Bosnia and Herzegovina (33% of kits), Croatia (27% of kits), Serbia (23% of kits). The branch's common ancestor lived about 17k years ago: the FTDNA Discover estimate runs from 15k to 20k years ago. YFull has 1,370 samples in this branch and dates its common ancestor to 15k years ago.

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.

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.

2 small sub-branches more without a page: 0 kits. On the branch itself, without a resolved sub-branch: 93 kits.

Surnames #

Surnames that testers entered at FTDNA, over the whole branch with its sub-branches: 124 distinct among 361 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%.

I-M423: 1,370 samples. The common ancestor lived 15k years ago (13k–16k); the branch split off 19k years ago (17k–20k).
