Isaac Gedney b. White Plains, Westchester Co., NY ca. 1700-9, d. 31JUL1771, m. 31JUL1736 Sybil Nelson, d/o Polycarpus and Ruth Nelson. Sybil’s father’s will (dated Mamaroneck, 3OCT1737) mentions his daughter, Sybil Gedney, wife of Isaac Gedney. It is possible that Sybil’s mother, Ruth, was also a Gedney, as Polycarpus mentions a brother-in-law, John Gedney. Of course, this may mean that his sister married John Gedney.
as 'Sebe's' Parents. Sybil Nelson, when married, was also referred to as 'Sebe'; possibly a nickname. I do not know for certain what children Isaac and Sybil had.
