The Stone Family Line

This family line, my husband's biological maternal line, has given me fits.  James' mother is Marcella Ann Stone, but she left when he was 4 and we have very little information about her.  While Searching Rootsweb earlier this week, I found a family tree for Jacob Stone, Sr. which had Marcella Ann Stone listed in it, along with her father's name, Dendle E. Stone.  I contacted the author of this tree, Bob Walton, and he sent me a pdf file of what he had on that branch of the tree.  Researching this side of the tree has two purposes; one is obviously to complete the tree, but also we hope to finally locate Marcella.  I now have new information to go on, names of her uncles, which may lead to new contacts.  We can only hope.
