This was over 6 years ago but the note I was making on info from a relative shows "3 sons - Elijah, Luther and Ruben".In the margin of the family record for Hezekiah Kinnicutt, b.9Jun1713 MA next to "Children: Luther 175?-1833" I show Rueben? and Elijah b.1770-80?. So far, I haven't found a thing on Rueben and haven't tied Elijah to Hezekiah. I tied Luther to Hezekiah by a hand-me-down listing, that only lists Luther as children.
Census show that Luther was in Dutchess Co NY in 1790 & 1800 and Westchester Co NY in 1810.
Census show that Elijah was in Dutchess Co NY in 1800 & 1810.
I have Jesse Purdy b. abt 1749 Westchester Co NY, Married abt 1768 NY City and d. 26Feb1817 Delaware Co NY
