Could this William have been the son of Reuben and Nancy Vandike Pruett/Prewitt? He was 15 years old in the 1850 Tazewell Co Census records. Not sure if they migrated to Buchanan Co or not. Bearwallow? Isn't that close to the Buchanan/Tazewell line. My grandparents used to live in a house that sat "smack dab" on the line. They always said they lived at Bearwallow when they lived in that house.
