You had detached two of his sons, one of whom had moved out to Calif. and died. There seemed to be a conflict, with the mothers not matching, and an overlap of dates making it seem as if he could not have married both women. However... the one out in California definitely had Tenn. roots, had a father of same name (actually living w/him in Calif.), and had other things that seemed promising. On the other hand, I think I saw another person of similar name out in California, and/or one that had a marriage in Illinois that overlapped in the same, impossible way. Anyway, do some work on this line!
