Following the earlier postings about the genetic origins of British people I have found the book I mentioned: Stephen Oppenheimer : The Origins of the British. Pubd by Constable in 2006. A fascinating book, which runs to over 400 pages. Basically, it tracks the genetic spread arising from the "refuges" occupied by humans during the last Ice Age (about 15,000 years ago). The vast majority of the "indigenous" population of W Europe - and I recognise the political dangers of such expressions - arise from three "refuge" populations, the male lines having been given names to make them more memorable: Ruisko - from the Iberian (Spanish/French) refuge. This is by far the dominant influence in Britain. Rostov - from the Ukranian refuge. This genetic marker is dominant in the Ukraine and Poland, and significant in modern Norway. It can be viewed as a "Viking marker" when seen in Britain. Ivan - from the Balkan refuge. Influential in modern Denmark and Holland. On p.369 of Oppenheimer's book there is a fascinating chart which shows the influence of these three genetic influences on samples taken in various parts of Britain. So, Rostov (the "Viking" marker) is strongest in Shetland, Orkney, with a lesser influence in Eastern Scotland and the Isle of Man. Ivan is found most commonly in Norfolk, and York. Samples taken in Haverfordwest, Castlerea, and among speakers of Irish Gaelic showed very strong Ruisko (Iberian) influence, with slightly less inflouence in samples from places like Oban, North Wales etc. On a very localised scale Llangefni (Anglesey) shows 96% Ruisko influence! Unfortunately there does not seem to have been any sampling in Warwickshire! Uttoxeter (Staffs) lies on a Ruisko/Ivan axis with weak Rostov influence. Intriguingly Uttoxeter is closer (genetically) to Belgium (or to a sample of Belgian males to be correct!) than it is to a Cornish sample, or even to a sample taken in York !! Sorry this is off-topic, but of interest I hope. Gwyn
