The latest evidence says not. It appears that the Celtic blood of Southern Britain still runs strong... Y Chromosomes Rewrite British History
I meant for the most part. Yes, there is still Celtic blood in the UK and in some places in southern England but the distance analysis I saw for the UK was 7 units away from those of Denmark (this is very close). And this was for the capitols of each country. And I would assume London would be included in 'southern England.'
I wonder what they mean by southern England (Wessex?)? Plus I wonder about the assumptions made with respect to normalizing the Y differences to the central Ireland population. As Ireland was subject to quite heavy Viking activity with lots of slave trading going on there.
I guess I would like to see some corroboration since much other evidence seems to refute their claims.
That is some cool stuff though, even with the caveats, and helps to further understand what the heck happened in England during that time.
I found out I have a distant relative in the Royal Air Force(same very uncommon last name).
