More on the Benajah family

More work on Benajah Sr.'s sons. 1. Dea. Benajah, (b. 1763, d. 1851) also lived in Lansing. He had a son named Benajah b. 1786 in Newburgh NY; Samuel, b. 1788 (birthplace unknow); Truman b. and Hinman D., b 1794 (unknown). Truman is listed as unmarried in Lansing in Dwight's as is Hinman D. These are in the same generation with Reuben.

2. Amos (b. 1771) lived in Lansing. He can be ruled out as the potential father, based on names in an 1825 deed conveying to legal heirs that named sons: Willis, Freeman, Amos, William, Hiram, and Charles.

3. Salmon (b. 1772) had many children but the first was born in 1797, too late for Reuben to be in his family.

4. Simeon Prime, (b. 1774) married in 1799 so also too late.

I believe this leaves us with either Benajah Sr being the father with children unlisted and born along the way like son Benajah's son somewhere in NY, or Jr. with an unlisted son somewhere along the line. Not too promising. Where's the missing link?
