The following website is devoted to the descendants of William Thompson and Margaret McCoy. http://members.aol.com/txcherind/thompson-mccoy_chickasaw-choctaw/ If you cannot access the site, then type in "McCoy-Thompson" in the search window at Google. There's lots of information here. When I examined the papers in the Scott Dumas application, I found some papers from these Thompsons mistakenly filed in the Dumas boxes. That's how I came upon the site. Kitty
