More than one well documened source that has confirmed that I descend from Somelred on my mother's side. I also have about 8 first cousins and their male children who should have direct Y lines to Somerled. One has done a Y-500 that someone else did for him but I don't have access to that kit but I'd like to have at least one Big Y 700 for that line. Some day the person who controls the Y 500 kit may upgrade but as I say I can't control that. My quesiton is, what advantage would there be to having multiple first cousins do a Big Y 700. Would having multiple kits help to confirm the direct line to Somerled any more than one kit would? Are there many people who have well sourced lines back to Somerled who have also done a Big Y 700?
