My gut is its Gideon also as father of Sarah.
Def not Isaac as he only has one female listed in the 1790 census, whereas Gideon has 2 and Abner has 3. Anyone have any info to rule Abner out?
I've got sooo many relatives on all my lines in Freetown I'm going to spend some time down there at the library and town hall sometime soon.
