Have very little information on Orin Hart. According to the family record book kept by his daughter, Nettie Forna Hart, Orin was born 12 March 1812 at Semponious, Cayuga Co., NY; married Clarissa A. Cornwell born 2 Dec. 1819.they married 31 November 1831 at Owasco, Cayuga Co., NY. Clarissa died in 1913 in Wolsey, Beadle Co., S.D. I have her obituary.
I beleive that John Hart was Orin's father. thank you.
