Benjamin Johnston b. abt 1734 m. Dorothy Jones and had a son Philip Johnston who wound up in Moniteau County, Missouri with Jeremiah Walker Clay. Philip had a son named Snelling b.1770 in Spotsylvania County, VA. This suggests there is a connection to Jonathan Johnston who married Priscilla Snelling in Middlesex County in 1721. The connection would link William Johnston/Anne Chew to John Johnston b. 1667 who married Lucina Blake in Middlesex County in 1686. Any help with this connection will be greatly appreciated.
