mtDNA haplogroup H6b
H6b is a branch of the FamilyTreeDNA mt tree with 50 kits that gave a country, counting all sub-branches. It is most common in these samples: Russia (Republic of Chechnya) (2.6% of kits), Saudi Arabia (0.7% of kits), Italy (0.2% of kits). The branch's common foremother lived about 7,800 years ago: the FTDNA Discover estimate runs from 6,900 to 8,800 years ago. YFull has 84 samples in this branch and dates its common foremother to 3,600 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.

Migration path #
How the branch's maternal line moved. Up to branch H, the path follows the Mitotree maps in FamilyTreeDNA Discover. After that, dotted, comes ftdnastat's estimate. It places each ancestor by the countries where the branch's FamilyTreeDNA customers live and routes the way between them over the terrain. Checked on Y branches: for half of the nodes younger than 6,000 years the estimate lies within 70–200 km of Discover's point, for older nodes, within about 550 km. Nodes older than 30,000 years were not checked. Dates are node ages.

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. The list has peoples with at least 30 samples, 3 or more of them in this branch.
- Chechens: 1.7% of samples (5 of 297)
Sub-branches #
Sub-branches that have their own page (50 kits or more), as a tree: every direct one, nested ones from 1% of the branch's kits. 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: 12 kits.
Sub-branches without a page #
These sub-branches have no page of their own: each has fewer than 50 kits with a country or is a junction with an apostrophe in its name. All such branches of the FTDNA mt tree are here, even those without kits, with their age and top countries.
- H6b2 23 kits 7,700 years Russia (Republic of Chechnya) 12, Italy 2, Russian Federation 2
- H6b1 15 kits 6,500 years Scotland 3, Bulgaria 2, Italy 2
Mitotree branches #
Mitotree is FamilyTreeDNA's new mt tree in Discover, version 2026.10.07 (Beta Release 12). Branches missing from the public tree appear here, under their nearest ancestor in it. Samples, age and countries come from Discover; some branches have only a name.

How old the branch is, by source #
Each source's estimate on one scale, in years ago. A dot is the estimate, a bar its spread (a 95% interval for YFull); no bar means the source publishes no spread. The “common foremother” rows show when the last common foremother of all carriers lived, the “split” rows when the branch broke off from its parent. Mitotree does not estimate the split, so its row shows the age of the parent branch itself.
New this month #
FTDNA: how much the kit count grew between the tree copies of 2026-10-02 and 2026-11-02. A kit that moved to a new sub-branch after refinement is not counted as new. YFull: samples YFull itself marks as new, in the copy of 2026-11-02; YFull drops the mark after a few weeks.

Ancient samples in the branch #
5 samples from excavations belong to this branch or its subbranches. Source: YFull; no culture given.
A dot is a sample, a line is the range it is dated to, the colour is its culture. A hollow dot: its placement on the tree is uncertain. The dashed line is the branch's common ancestor as FTDNA Discover estimates it.
