Robert Dallas (1756-1839) m. 1781 Bedford Co. VA to Nancy Turner (1765-1848). They lived in Goose Creek area, and later moved to Pittsylvania Co. VA. Dallas children: Stephen, Terry, William, Meredith, Seeny, Lockey, Bird, Jabez Leftwich, Arthur G., and John Thomas.
Robert must have been related to the other Marmaduke Dallases and John Dallases; plus others there. And who were Nancy Turner's parents? I suspect maybe Isaiah Turner (wife Frances Terry ?). Possibly a Leftwich connection, too.
