According to my Edward Doty book there is no proof Moses Cooper m. Mary Doty. It says he m. Mary Coleman. Moses was born in Southampton, Long Island, NY and lived there until his children were grown. At least two of his children married there before he and entire family moved to PA. The will of Samuel Coleman of Roxbury, NJ dtd 16 July 1773 and proved 29 July 1773 mentions his daughter Mary Cooper showing she was still alive in 1773. No record of any marriage to Mary Doty has been found in NJ records. Perhaps new info has come to light about Mary Doty and someone who reads this message will provide it.
