My daughter was researching my family tree and found this site. My maidian name is Tyndall. My Father's name is William Ralph Tyndall, his father was James Thomas Tyndall (born March 4, 1884), and his father was Joseph Tyndall. This Joseph Tyndall could be the Joseph Tyndall with the wife unknown. My great grandfather, Joseph Tyndall's wife's name was Mary Charbotte (not sure if last name is correct). We do not know if they had a child named Jim. The time frame fits for Joseph Tyndall. We do not know if it is the right Joseph Tyndall though. If you find any more information, or if this the right Joseph Tyndall, please let me know.
