Hi All This is very interesting. I came across a fellow Millward researcher who told me he has the gene- been tested - and he was told it was from miners from the Iberian Penninusla (Spain) who had come to Derbyshire mines some centuries ago. He also understood that it goes down the male line. Is that so? I do have many Derbyshire families in my line. I went to the Doctor for skin cancer check - and he asked me where I got my Spanish skin from - fine and evenly pigmented. He had worked in Spain for some years. regards Hilary Thomas Melbourne nee Nottingham
