The y chromosome and autosomal difference between Wales and England is massive in nature. Look at most PCA's that come back in most studies. Wales differs substantially enough from the rest of the UK that it is surprising that the Welsh are located in the UK.

In the new page regarding ancient DNA in Britain, you don't mention where the samples are from. It would be great if someone could mention the exact location of each sample

Hi, A number of ancient samples are listed on the "genetic analysis of ancient Britain" page. It would be great to know the exact location where each of them was found.

Newer isn't always better. The one you posted seems to have some problems. 1) Does not replicate the result that has been replicated many times: the closest relatives to the Welsh (and Celts more broadly possibly) on the continent are the west Germans. 2) Level of Norwegian DNA in Ireland could...

The image you posted is from another study. Not the one I am citing. Admittedly the image you have posted is from a more recent study. In the image you show, the Spanish component in Wales does indeed look comparable to the rest of the UK. in POBI 2015, they obtained different results based on...

You bring up some really great points Jovialis

Maciamo, the reality is that many studies show the great German migration and other events like the Roman Empire to have had little impact on the DNA of other peoples. Many studies show that local genetic structure has been in place for a very long time at least until recently. And finally...

A lot of stuff on this site is baseless armchair science. Look at the POBI study again. Look at the figure mapping continental European genetic clusters to different regions in the British Isles. Look at the UK average for Spain (labeled SFS 31). Look at the amount of SFS 31 in North Wales. You...

I appreciate all the work you are doing, but you have to stop speaking like an authority on these matters when I don't believe you are. Academic study, after academic study, can find close to 0 genetic impacts of the Romans throughout many of the places they colonized. Not to mention the Romans...

Due to how new I am to this forum I cannot post links. I will name the Sources best I can: 1) People of the British Isles 2015 2) Distribution of European MTDNA haplogroups by region in percentage, from Eupedia website 3) 23andMe info page on British & Irish Ancestry "Welsh Connection" For...

The Welsh have orders of magnitude more DNA related to Spain according to that Paper. The Welsh also have a considerable amount of a French component that maps to Central/Southern France. It is absent in much of the UK except a few other Celtic groups. It peaks in South Wales. There is a German...

The distribution of Caucasian DNA in Europe is frankly pretty unbelievable and perplexing. There is 10% in Belgians and only 4% in Dutch. It is damn near absent in Scandinavians, and over 10% in Polish people. And yet it is 3% in Russians. It is 20% in Sardinians, close to 10% in much of Spain...

The evidence is convincing that the blood of the Neolithic inhabitants of Wales runs strong in the modern Welsh. It is unlikely that the 90% replacement took place in Wales.

There is a huge problem here. We need to know WHERE and WHEN these samples all come from. And it would be good to know if there have been any further analyses of these samples either in academic studies or in forums like this. For example, the only Visigoth samples I'm aware of are from Spain...
