I would like to contact any male that is a descendant of John Snow and Sally Sara Gammon married 30 June 1790 at St. Paul’s church, Halifax. That would need to be a male from a male from a male etc. back to this family. I would be willing to pay for DNA testing for such a person. I am trying to surmount a brick wall in my family tree. I’.m looking for the origin of Henry Snow born 1796/7.in N.S possibly around Lawrence Town or Porters Lake. Wally Snow
