FTDNA mt-tree branch

J1b1a1a

J1b1a1a is a branch of the FamilyTreeDNA mt tree with 340 kits that gave a country, counting all sub-branches. It is most common in these samples: Iceland (2.9% of kits), England (Cornish) (2.5% of kits), Northern Ireland (1.6% of kits). FTDNA Discover publishes no age for this branch; YFull's, when it has one, is below. YFull has 93 samples in this branch and dates its common foremother to 800 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.

YFull

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.

No sub-branch has its own page: only small branches lie below.

On the branch itself, without a resolved sub-branch: 340 kits.

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%.

J1b1a1a: 93 samples. The common foremother lived 800 years ago (700–800); the branch split off 2,000 years ago (2,000–2,100).
