I have a sheet from a book on will abstracts in Richmond Co., VA, which includes the following:
"p.157 - George Yerby, NFP, will 23 May 1785, 3 Jun 1793, all land in Rich. Co. to be eq. div. between my two sons George and John M.; land in Fairfax lying on Pohick to be sold; sons also to receive lands in (?) Cp.; daus. Sarah M., Nancy, Judith G., and Betsy; (?) sons to have a good education; ex: friends William Miskell, John Fauntleroy, Abner Dobyns, and Thadd Williams; wits; Chichester Tapscott, Sally Keyser, Ellin Ball Glascock. (George Yerby mar. (2) Elizabeth Rust Farland, dau of Griffin Garland in 1790.MR(?) p. 238.)"
Some of the question marks are due to my poor copy.I have no further information on these people.
