I am trying to locate Mary's parents. Mary was married to Tunstall Ferguson of Pittsylvania County about 1818. She had one child Martha Jane Ferguson bn. 1819 and died about 1821. Mary's mother's raised Martha Jane and was known as Susie. I have found several Martin families that could be her parents. Robert Martin and Susannah Ray or Wray, md. 13 Feb. 1798, in Franklin County,Robert Martin and Susannah Robinson, md 16 Dec 1799 Franklin County, and John Martin and Susannah Joetz, md. 1789 in Pittsylvania County. Mary had two sister, Deliah Martin and Betsy Martin.
