I did a little more research on Asher Pipkin Fly and Marilla Elizabeth Cantrell. I found them in the 1850 census, listing the following children: Eliza (22), Albert (21 and married to Sopha, 19), Sarah (21 - possibly a twin of Albert?), Jeremiah (17), Elizabeth (15), Tillman G. (13), Jonathan (11), Rachel (9), Margaret (7), John (6), Elvina (4), and Arteleta (1). It is possible there were older children also, since Eliza would have been born when her mother was 24, and that was pretty old for a first child back in that time period. I will keep looking and let you know if I learn any more.
