The Cornish gene

Here's a heatmap of M269 descendants. Their name for M529 - me - is "S145".

S145 clusters in Brittany (62.5%) and, to a lesser extent, in England and in other bits of northern near-coastal France. I am told M529 / "R1b1a2a1a2c" is also common in Ireland. Here I'm interested in Brittany as a time-capsule of ancient southwestern Britain.

My understanding of Brittany is that it got swamped by Cornishmen during the Dark Age (Gildas, for instance) and then didn't change much. The Breton language is, well, British and not a descendant of old Gaulish. The genetics seem to back this up: back when Cornwall was mostly S145, their men came to Brittany. Only after this, has Britain's S145 population diluted (to 46%). I'll bet you S145 remains more common in Cornwall than it is in the rest of Britain.
