Hi Katherine, I am really confused on this line.I have that Robert Allen is the son of William W. Duffer and Rebecca Hawkins Duffer.I have that he married Elizabeth "Betsy" Flippin. I have an unidentified female; Abner B. who md Malvina D. Bell;Wm. Seaton md Frances A. Winn;Emily md Isaac Caldwell; Harriet md Geo. Gillespie;J. E.;Richard md Nancy Hicks.Am I on track?My line is Seaton Duffer, Edw. S; Robert Sam'l;Alfred Seaton Duffer.
Unfortunately I have nothing beyond Isaac. I did see a name John offered as the father of Isaac but nothing other than that - no proof.
