Mary Peay and John Coats Cox Vernon are in my direct line, too.My understanding is that John and Mary had a daughter named Hibernia E. I. (b. May 12, 1830 in Rockingham County, NC, d. Dec 5, 1864, Manor, Travis County, Texas) who married John Edward Raney (b. Feb 12, 1824 in Williamson County, TN, d. Dec 14, 1901, Manor, Travis County, Texas) on Jan 31, 1849 in Rutherford County, TN.Hibernia had a daughter named Mary Frances Raney (b. Nov 19, 1849 in Williamson County, TN, d. Feb 15, 1947 in Austin, Texas) who married Dr. John Davidson Fields, (b. Apr 19, 1845, in Abdington, Virginia,d. June 27, 1925 at Austin, Texas) on Oct 24, 1866 at Travis County, Texas.They had a son named William John Fields(b. Oct 3, 1868 at Travis County, Texas, died March 23, 1939 at San Angelo, Tom Green County, TX) who married Viola Gibbons.(I have additional information on this family if you are interested but theis is getting rather long)They had six children, the elsest being Thelma Francis Fields, my grandmother.Where does your line start?
