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.

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.
- English: 2.0% of samples (21 of 1,050)
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 ancestor lived.
21 small sub-branches more without a page: 191 kits. On the branch itself, without a resolved sub-branch: 187 kits.
Surnames #
Surnames that testers entered at FTDNA, over the whole branch with its sub-branches: 79 distinct among 318 kits. FTDNA gives surnames per branch only, with no country attached, so they cannot be split by country.

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%.
I-Y4751: 216 samples. The common ancestor lived 1,600 years ago (1,400–1,800); the branch split off 1,600 years ago (1,300–1,900).
