FTDNA Y-tree branch

Haplogroup N-BY10355

N-BY10355 is a branch of the FamilyTreeDNA Y tree with 51 kits that gave a country, counting all sub-branches. It is most common in these samples: Russia (Republic of Mordovia) (5.8% of kits), Russian Federation (0.4% of kits). The branch's common ancestor lived about 3,400 years ago: the FTDNA Discover estimate runs from 2,800 to 4,000 years ago. YFull has 57 samples in this branch and dates its common ancestor to 3,300 years ago.

Belongs to the N-M178 branch, which has a note.

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.

Colour is the branch's share of the country's kits. Hover over a country or tap it.

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.

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 ancestor lived.

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

Also 1 small sub-branch of under 5 kits: 2 kits in all.

Sub-branches without a page #

Each of these sub-branches has fewer than 50 kits with a country, so none has its own page. Below are all with 5 or more kits, with their age and top countries.

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 ancestor” rows show when the last common ancestor of all carriers lived, the “split” rows when the branch broke off from its parent. Discover does not estimate the split, so its row shows the age of the parent branch itself.

How the branch grew #

How many sub-branches already existed at each moment: a sub-branch counts from the time its common ancestor lived (FamilyTreeDNA Discover estimates). Sub-branches with a known age: 43.

0 1,000 2,000 3,000 1 10

explosive growth: the number of sub-branches doubles in under 400 yearsgrowth: the number doubles in 400–1,500 yearsstagnation: no doubling within 1,500 yearsgrey: fewer than 5 sub-branches at the start of a stretch — too little to tell the rate

Across: years ago; up: number of sub-branches, log scale. The shaded band marks the period when the count multiplied most; the last thousand years are left out.

The branch grew fastest 1,500–1,000 years ago: its sub-branches went from 15 to 23.

Sub-branches of the last centuries show up only where many relatives have tested, so the right end of the curve says more about who took a test than about population growth.

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.

Surnames #

Surnames that testers entered at FTDNA, over the whole branch with its sub-branches: 1 distinct among 2 kits. FTDNA gives surnames per branch only, with no country attached, so they cannot be split by country.
