I'm looking for the ancestors of Thomas, born 1750-1760 and his son, (my gr gr grandfather) Justus Clark, born 7 Jan 1788. He was born in NY, probably Saratoga, and settled in Sullivan County, Ind. And then I found an Abraham Clark (1736-1817) who had a son named Thomas (1753) born in Elizabethtown, Essex, New York. I'm wondering if this Thomas is the same as my Thomas? Thank you for any help you can give me.
