I know you posted this long ago, but I just ran across it. Rebecca and Abraham Cain had a daughter, also named Rebecca. She married Reese Winters, they were my gg-grandparents. Rebecca Jr died about 1834. Resse remarried, also to a Marshall, Pricilla Marshall. I do not know the relationship between the two wives, maybe cousins? I don't know anything about Abraham Cain (Cane/Kane) beyond that.
