No source is given for her maiden name, and it might reflect confusion with another John and Mary Godsey couple in Tennessee at around the same time (there were 2 such couples in the 1880 census).
born 17 Aug 1898 in Grassy Cove, Cumberland parents: John Godsey and Mary Edwards filed 20 Oct 1943
Betty's mother's maiden name conflicts with that given on the death certificate of her sister Clara. A possible explanation is that Mary remarried after John's death and her new married name was Edwards, and that is the name given in this delayed birth registration. The 1900 census implies that Clara and Mary had the same mother, since John and Mary had been married for 26 years.
