I have just finished doing some research on Elnathan Wilcox who was born 10 Feb 1733/4 in Killingworth, Middlesex, CT. and found that he is not the same on who died 25 May 1826 at East Bloomfield, Ont., NY.
the first one was married to a Thankful Bennett, and the second one to a Hannah. I have found that Hannah was married first to someone else before marring Elnathan. She might not be a Adams. I have more information.
