I finally found a readable copy of the UK DNA study map. It is in the March 2015 newsletter (number 6) of the People of the British Isles web site, in a PDF file. The URL is: http://www.peopleofthebritishisles.org/nl6.pdf The PDF file of the newsletter has 10 pages. The map is on page 4, immediately after this text: "The first and most striking observation is the extraordinary correspondence between the genetic clusters and geographical location. Most obvious at a first glance is the distinctiveness of the genetic clusters in Orkney, which is perhaps not surprising given that Orkney was a Norse Earldom for several hundred years. Also striking is the clear separation of the Welsh clusters (green and pink squares, yellow inverted triangles) from the rest of the UK, and the extraordinary separation between Cornwall (pink crosses) and Devon (blue circles)."
