I have no idea who is Elizabeth except maybe a daughter or daughter-in-law of Ephraim. I was aware that Mary was not in the same household. It appears that in the 1870 census of Elizabeth she is gethering her children together and the census list her as: E. A. Frady age 36, J(oseph E(phraim) age 18, MARY age 16, James H. age 14, Lilly age 10, Kitty age 5. Here are my best thoughts. Elizabeth is the daughter of Ephraim and keeps having children by different men.She is still having children after the 1860 census. Joseph E(phraim) and James H. went to Carrol County Miss. J. H. married Nellie BurtDec. 1884. It appears James H. first married E. Amanda ? and had one daughter Rosallee and James H. left her before 1884. His wife Amanda is living alone in Henderson Ciounty in the 1900 census. Lilly and Mary Frady Harper are found on page 264 of the 1880 Henderson County census. Kitty ( Sarah) is living with Sarah Pittillo Leadbetter as a neice on page 340 1880 Hooper Creek Hnederson County census. Sarah Pittillo Leadbetter is the daughter of Ephraim. W. Riley did not join Elizabeth in the 1770 censu but is still living with T. O. Roberts on Flat creek page 178 Buncombe County 1870 Buncombe Countycensus. You may be right he must have died as I have not found him again in any state census -such as --NC. SC. Tenn. Ga. Al. Miss., Tx. Fla. etc..
