I descend from a William Johnson, who is the possible William Johnson that once lived on Mark's Creek. He died in 1805 in Johnston County. He was referred to as William Johnson of Wake County when he bought land in Johnston County in 1784. Dna testing has proved this William was not related to President Andrew Johnson or the Sill Johnson line. He was not of the Isle of Wight line Johnsons either though his wife Mildred Johnson was. William's son Noel Johnson is my ggg grandfather. He had a son named Aaron.
