I am trying to locate proof of the parents of Stephen Ryerson who was born in Dutchess Co. 9 Feb 1763. In a family sketch in the History of Stokes Co., NC Vol. 1 it says: "The names of the parents are not known but the Ryerson family is an old one in New Netherland, the brothers Adrian and Martin Ryerson coming to New Amsterdam in the 1640s." Some online sources have suggested that Adrain and/or Martin could be his father but that is extremely doubtful unless the Adrian and Martin who came in the 1640s had descendants with the same names. I've never done research in Dutchess County and am not familiar with what sources are availabele for the period time I need. Your advice and help will be appreciated. Connie
