If we¡¯re agreed that CTS4466 probably didn¡¯t form on the island of Ireland, but in Wales
If CTS4466 TMRCA is 250CE then IMO it clearly increases the likelyhood of it being of Irish rather than Welsh origin.??
?
I will point out (again) that FGC11134 (parent of CTS4466) remains were carbon dated in:
- Fermanagh (4370-4156 ybp)
- Sligo (4036-3779 ybp)
?
As has been noted in this group there is zero known small scale elite migration to Ireland from the native Welsh (with the possible exception of the Roman conquest of Mon c. 80AD) in the first part of the first millennium CE.
?
There IS some ¡°elite¡±/small scale return migration recorded of Irish settlers living in Wales BACK to Ireland plus PLENTY of recorded migration of Irish migration to Wales 100BCE-450CE, including starting royal dynasties there.
