Hi Claude, Go to www.ysearch.org which is where comparisons can be made. Richard Hill's web site is www-dna-testing-adviser.com/Richards-DNA-Project.html This can be both exciting and tedious exercise trying to find the answers. I sure have been down a few wrong trails Claude but just recently I have scored some correct answers and it keeps me fired up to do more research. I have recently travelled to Waterloo in Belgium. My Forebear, Lt Loftus Richards fought with the 71st Highland Light Infantry against Napoleon on that pivotal day in 1815. Maybe he was your forebear too Claude?
