• He sailed to America in 1856 on the ship Thornton. 

  FamilySearch shows that John Roberts married a woman by the name of "Mary Bubb," but the marriage record in England shows her maiden name as "Babb." 

  England marriage records show John Roberts marrying a woman by the name of "Mary Babb."   Indications are that she may not be the Mary Bubb that John married.   Mary Roberts and a John Roberts were on the same ship, but the ship manifest lists them on separate pages, not traveling together as a family.  Further research is needed to determine if they were indeed man and wife.
