Marshall - I know that the marriage index lists Abraham Plummer as Syntha Ann's father; however, there is a land dispute in Fleming county over the land Isaac Plummer bought from Michael Haynes after Abraham Plummer had died. In this lawsuit, the heirs of Abraham Plummer are listed as Nelson, Elizabeth, Ann Veatch, Mary, Soloman, Sally and Nellie, dec'd. Since Syntha was alive and living in the area at this time, I don't think she is the daughter of Abraham. The younger Abraham, the son of William C. Plummer, may have posted the bond or signed for Syntha Ann, and she is probably related to the Isaac Plummer family somehow, but I haven't been able to prove which family she belongs in. Sorry I can't be of more help. Roxann Shafer
