I have just received a DNA report, which, combined with my paper trail, indicates that I descend from Robert Stewart of Milford/Norwalk. I think it is very possible that he came over on the John and Mary in 1651/1652. However, my Y-DNA supposedly indicates that I descend from Sir John Stewart of Bonkyll (s781.org). If this is true, our Robert could not be the son of Francis and Isobel. Of course this is tentative and difficult to prove, but as more data comes in, we may get a clearer picture. If only Robert Stewart had uploaded his family tree!
