I1a1
I1a1 is a branch of the FamilyTreeDNA mt tree with 928 kits that gave a country, counting all sub-branches. It is most common in these samples: Iceland (4.4% of kits), Wales (2.6% of kits), Scotland (1.9% of kits). FTDNA Discover publishes no age for this branch; YFull's, when it has one, is below. YFull has 346 samples in this branch and dates its common foremother to 2,000 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 foremother lived.
1 small sub-branch more without a page: 38 kits. On the branch itself, without a resolved sub-branch: 175 kits.
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%.
I1a1: 346 samples. The common foremother lived 2,000 years ago (1,800–2,100); the branch split off 20k years ago (20k–20k).
