Just read your post of 8 Jul 2011. Melvin and Camelia are my GG grandparents. I descend from Francis through his son John Henry and from his son Melvin through his daughter, Rebecca Caroline.
John Henry's son John C. married Melvin's daughter, Rebecca Caroline. Their daughter, Stella, is my grandmother.
Have information on Melvin's family which I am willing to share if you did not receive what you want from you 2011 post.
