Thank you for your reply. How might I contact Sue Wilson?
My info about Solomon Sturdivant being married to Maria Higley comes from the book "The Higleys and Their Ancestry" by M. Coffin Johnson published as a second edition by Grafton Press in 1896.
I have been in contact with David Stirdivant of California who believes he is directly decended from Solomon and Maria Stirdivant, whom he refers to as Polly Marie. His line does go through Sheboygan, WI. The Higley book states that Maria's parents were Timothy and Polly Allen Higley.
