I am seeking information regarding Joel Bishop and his wife Maria Head. According to Landmarks of Tompkins County, Family Sketches, GRAVES, Mary Jane BISHOP, was born in the village of Ithaca, May 13, 1829, the eldest of five children of Joel and Maria BISHOP who were natives of Lansing. They soon, however, removed to Dryden, where Mr. BISHOP engaged in the manufacture of guns. He was a son of Dr. James BISHOP. Mary's sister, Anna Bishop, married Uriah Clark. Their daughter, Georgiana, married Truman Parker. Georgiana and Truman are my great-grand parents. Joel and Maria seem to be my brick wall, and I would appreciate any help.
