Let me refer you to a Rootsweb response from Ernie Ashby on this subject. His e-mail address is in this excerpt and you may want to make contact.
"Getting back to John W. his first wife was Frances, LNU and they had one child, William, born abt 1798. Frances died abt 1799 in Stokes Co. NC. John W. married Mourning Guthrie in 1802 in Halifax Co. Va. and was a witness to the 1805 marriage of Cuthbert Ashby and Nancy Lands in Halifax Co. Va. Both families moved to Stokes Co. NC and lived near each other until after 1830 when Cuthbert moved his family to Russell Co. Va. John W. died in 1857 in Stokes Co. NC
