John F. Williams died in Hardin County, Kentucky, where he left a will dated 6 March 1814 which was proven on 11 July 1814. As far as I can tell, this John was not a member of the extended Williams family of Cumberland County, Virginia as they migrated westward.
As a follow up, I checked online trees and this man is said to be John Fenley Williams, born 1756 in Prince Georges County, Maryland. He was the son of Thomas Williams and Elizabeth Gibbs and married Ann Mudd there in 1782.
Therefore, these enslaved people may have been brought to Kentucky from Prince Georges County, Maryland with the Williams family.
