John Presley, son of Andrew, Jr. is the father of Dunning (Dunnan) Presley. Dunning, Sr. is listed by himself on the 1810 Buncombe County Census, and on the 1820 census record for Buncombe County, NC, along with John Presley. It is now believed that John Presley may have been married to a Casiah/Keziah, daughter of Dunning Casiah [appears in conflict with other sources], the neighbour of Andrew Prestley, and whose other daughter, Mary Polly Keziah, married Andrew's eldest son, Charles. John's son, Dunning John Presley, providing that his mother was a Casiah, would have been, in Tuscarora tradition, named for the maternal grandfather, in this case, DUNNING Casiah.
