Elizabeth Keesee is a real person, there’s a Pittsylvania County, Virginia marriage record for her and Claiborne Hicks in 1787; Claiborne is on the 1820 census in VA, over 45 with woman over 45, so probably the same couple. It’s her bogus Indian parents that are the problem, she seems to have real parents on some trees and there are multiple records for people named Keesee in Pittsylvania County at that time.
