Thank you for that info.Last I corresponded with David, we were concentrating on William Frazier and trying to find out more about his wife(s).I have been trying to find the death certificates of both Mary Sina and Jenette to see if it lists the parents, trying to verify the mother.
The (Mary)Sina Daffron in Oregon County would be the right one.So that narrows it down a bit when and where she died.
Sina Daffron, daughter of Elmer, would be Mary Sina's great-granddaughter. Elmer was the son of John, Mary Sina's first child. (First, I think)
My husband is a descendant of Robert Frazier, brother to Mary Sina and Jenette.
Again, thanks for the direction.And good luck to you in your own search.I love the puzzle!
