I am looking for information on a William St. Clair. Born around 1790, possibly New Jersey. He married Sarah Ann Dixon. Both are supposed to be natives of New Jersey, and of French descent. A story passed down, claims that one of the St. clair's changed their name to St. Clair from ? Possibly political? They had a son Charles H St. Clair born 1840 in New Jersey. He married Maria J. Tremper in 1860 and had 7 children. Resided in Wahstenaw County, Michigan. Any info would be appreciated, thanks.
