  • Notes: 

  • Some of the descendants of Joseph Richardson and Mary Dugan have claimed that Mary is the daughter of Jeremiah Dungan and Deborah Drake. This appears to be wishful thinking as Mary Dungan is said to have married Abraham Vanhorn and not Joseph Richardson. Mary was Abraham's first wife and died before him as he remarried after her death to Mary Van Sciver.
