Wife Eleanor Thomas was the daughter of Edward Thomas and Mary Johnson.
William was a known Justice of the Peace in 1820.
Sister Sarah King was a spinster.
The both resided in the Frederick County area, mainly around Frederick itself, although he did own some land in farther areas. "Silver Branch" 7+ acres was part of "Resurvey on Hazzard" which was in Washington County.
I have tons of information on William as far as legal proceedings, debts/debtors but very little information on how he relates to other King families in the area. Two of his known children are Thomas R. King and Sarah King, these names seem to be very popular within the King families in this area.
Any insight or clues would be greatly welcome!
