Hi Elise, This family is not in the Daniel Piatt line of NJ and KY. I too corresponded with Robert Alexander Piatt starting back in 1985. The best I could learn was that John, born 1782-83, married Hanah. They had a son John married to IBBA BROOKS. John and Ibba were the parents of John C. Piatt, born 1861. John C. Piatt died May 27, 1930. Hope this helps. Dick
