I believe this William is the brother of John of neighboring Rutherford County, NC., who married Dirisa Lunsford in 1828. His father was Killes Alford who married Elizabeth Jones in 1795 and later moved to Kentucky after Elizabeth died about 1808-1810. Killes' father was ol'John of Rutherford County in land records of 1782 and census of 1790. Killes, with a couple of brothers, were mentioned in the sale of the property.
Killes son, John, was the one that moved to Knox County, KY in 1828, with Dirisa Lunsford. His son, Daniel, was the father of my great-grandfather, James (Jim Doe) Alford. James' son, Homer, was my grandfather and the father of Bill Alford, my Dad. My name is Ken.
