Joseph and Priscilla lived at Tiller's Ferry, Kershaw District, SC, part now Lee County. He was in the area by 1759 when he had surveyed a plat for 100 acres. Joseph petitioned the South Carolina General Assembly to operate the ferry in 1791.

South Carolina Historical Magazine, Vol. 81. gives his dates as 1720-1801 and says that he was born in England and settled on the forks of Lynches River establishing a community there. He was buried at Tiller's Church (later called Bethany), but I don't think the grave is marked.
