I've been looking at your wife's Edwards ancestors.There's a theory (unproven) that this line leads back to Sylvanus Stokes.
Amzy Riggins d. of James Riggins and Margaret EDWARDS
Margaret Edwards d. of Starling (Sterling) Edwards, b. Feb. 6, 1768, Orange Co., NC; d. 1818, Ashe Co., NC; and Salena Cobb, Mar. 17, 1793, Lincoln Co., NC (b. 1770-1780; d. Oct. 1859).
Sterling Edwards s. of David Edwards, Sr., born c. 1740's; d. Dec. 6, 1782, Orange Co., NC; and Elizabeth Morris (b. c.1740's; d. Oct. 13, 1827, Bedford, Lawrence Co., IN) [Elizabeth Morris Edwards m. 2nd Richard Williams, becoming stepmother of James Pace's neighbor Vinson Williams; I would look hard for a marital link between James Pace and the Edwards/Williams family]
David Edwards Sr s. of John Edwards Sr (d. 1801 Orange Co NC) and Mary STOKES who, it is suggested, might be a granddaughter of Sylvanus Stokes Sr.
