Haplogroup R-S7432
R-S7432 is a branch of the FamilyTreeDNA Y tree with 50 kits that gave a country, counting all sub-branches. It is most common in these samples: Scotland (0.1% of kits), Northern Ireland (0.2% of kits), Ireland (0.0% of kits). The branch's common ancestor lived about 4,300 years ago: the FTDNA Discover estimate runs from 3,600 to 5,100 years ago.
Belongs to the R-DF27 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.
Where the ancestors of FamilyTreeDNA geographic project members on this branch lived, from the project maps as of 2026-10-20. Colour is the branch's share of the members at a place, or the number of its carriers; places with fewer than three are left blank. The centre and the 68% circle are corrected for some countries testing more than others. This is a picture of the sample: members chose whether to join and which place to give.

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.
On the branch itself, without a resolved sub-branch: 2 kits.
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: 40.
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
The branch grew fastest 1,500–1,000 years ago: its sub-branches went from 8 to 15.
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: 3 distinct among 19 kits. FTDNA gives surnames per branch only, with no country attached, so they cannot be split by country.
