John Goad left a will in 1771 Bedford County, Va. naming a daughter Ann Risdin, married likely to William Risdin. Supposedly they went to Wilkes County, N.Car. I think they were likely the parents of Phana (Risdin) Brewer.
Risdin/Risdon/Roysdon had a dozen spellings.
Go to the "RISDON family genealogy forum" and type in "Goad" and read messages I just posted for more details.
