X2b
X2b is a branch of the FamilyTreeDNA mt tree with 887 kits that gave a country, counting all sub-branches. It is most common in these samples: France (1.9% of kits), Moldova (1.7% of kits), Albania (1.7% of kits). The branch's common foremother lived about 9,000 years ago: the FTDNA Discover estimate runs from 9,000 to 9,100 years ago. YFull has 507 samples in this branch and dates its common foremother to 1,900 years ago.
Where it is found #
Countries and regions given by the branch's carriers. “Share of branch” is the part of the branch's kits that belongs to the country. “Share of country” is the part of that country's kits that falls into the branch; it is computed only for countries with at least 50 kits.

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.
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.
On the branch itself, without a resolved sub-branch: 27 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%.
X2b: 507 samples. The common foremother lived 1,900 years ago (1,800–2,100); the branch split off 20k years ago (20k–20k).
