• Notes

  By at least 10 autsomal triangulations with Rachel Dubois of Northern Liberties and her grandfather, Louis Dubois, we know that either this Mary's last name is Dubois or Gentleman John's mother's maiden name is Dubois. I have not been ao currently find a Mary Dubois of the correct age who is unmaried who could account for this Mary to explain the dna triangulations between Dubois and Gentleman John Coate.
