I can't do much about what was displayed on Dr Grierson's laptop but I wouldn't be surprised if North Wales was studied in particular because South Wales saw a large influx of English people to the coal mines and iron foundries during the Industrial Revolution. Hence, North Wales contains more men that belong to  "Old Welsh" lines than South Wales does.

It would have been helpful though if he had said so! Common fault I find with Academics in general.

I think that it is generally known that South Wales inhabitants are not all 'Welsh' by ancestry.
My Mum's family is from South Wales and she has Irish, English, Welsh and Greek ancestry.
Cardiff inhabitants came from all over the world.

Nor are the North Welsh if you go back a bit further!    L21/S145 is not a Welsh mutation per se, most think it is Central European, i.e. France, Germany, Switzerland, in origin.

The question is when did different L21 people arrive in Britain. Seeing as L21 is more frequent West of the Anglo-Saxon built Offas Dyke, the inference is that L21 was more common in Pre-Anglo-Saxon Britains than in Post-Anglo-Saxon ones.

Actually, there has been quite a few tests carried out in the South of Wales over the last few years. The migration story is a bit over exaggerated to.

Genetic tests released by Wellcome Trust in 2012 revealed that many South Welsh are also indigenous. And apparently there has been less immigration into Wales than anywhere else.

There are thousands of new genetic tests being carried out by Cymru/Wales DNA. And the South will be included to. According to the results so far, there are remnants of the Pioneers who migrated into Britain after the ice melted found in Wales, especially the South region. But it seems as if there is a strong genetic connection with the later Neolithic Beaker People.

I will dig out a few links soon!

The Origins of the British by Stephen Oppenheimer traces the DNA history of Britain and is very interesting. My 7th cousins are organising the DNA project for my mother's family, Broadley (includes  related people named Bradley) and they are L21. The Broadley family comes from Halifax in Yorkshire. claytonbradley
