I know you posted a long time ago. If you still haven't found our about John Fitch Bishop, I have his parents names. The father is John Bishop and his mother is Experience Harris. He is listed as just John but all the other family names fit. He is listed in the New Hampshire Birth Records, Early to 1900 on FamilySearch.org. "John Bishop birth; 13 Jul 1772- Chesterfield, Cheshire, New Hampshire; Parents, John Bishop, Experance."
