Historically speaking, the Welsh are the only true “British.” They’re descended from the original “British” who were conquered by the Romans.
The English came in after the Romans left (wise decision on their part) and took over most of the island, forcing the original British back into Wales, Cornwall and even across the sea into Brittany. The English (and everybody else on the islands) were eventually conquered by Normans from France.
The Scots, at least by that name, were originally invaders from Ireland into the northern part of GB.
Of course, all of this is largely genetically meaningless since the various original stocks have been enthusiastically cross-breeding for a couple millenia.
Yes, I truly know. It’s just so much fun to make light of it all — especially if you’re as scrambled as most of us are here in the States. I understand that England didn’t actually become “England” until the Anglos came in with that brat William. My mother’s side of the family came from all the places anyone could come from on the islands — Scotland/Ireland and Wales, including some who pushed in with William. Assume there must be a Roman or two in the wood pile as well. I’m such an amalgam of the UK, I can’t imagine WHAT I truly am. Pure German on my father’s side. Combine that with Cherokee and my, my I’m a mess. A regular patchwork quilt. The kid in this contest must be another amalgam. That’s were this whole thing started. Definitely can’t see the Welsh genes.
Breeding is good. I'm all for breeding.
