I sure wish I could help.Richard is believed to have had 4 wives:Mary, Unknown, Amelia Miller and Naomi Villers Gregg (widow).
Here's what I show in my notes: The Bertha Sellers Dotson information, Barr Wilson and the Franks Family history say that Richard married a Sarah Jeanne Hollyday about 1772.No documentation of this marriage has been found, nor has she been documented as parent to any children for whom we have record. When Richard's son William, born about 1776, died, his parents were listed as Richard and Mary.Probably around 1797, Richard married Amelia"Millie" Miller.However, Zachariah b. 1798, a son of Richard and Amelia, is shown as a half-brother to Richard Jr., born 1795 suggesting a wife between Mary, mother to William born in 1776, and Zachariah born in 1798. A fourth wife, Naomi Villers Gregg has been documented.
