I have also been reseaching the Cooks of Steuben County who were my family. I am familiar with David and Jonathan who settled in Upstate NY. My "deadend" is my direct descendant Epenetus Cook (b. 1786)who appeared in the census of 1810 at age 24 next to other Cooks... David, David Jr, Samuel, and Silas. I do not believe he was one of David's children (Levi,David, Jacob, Samuel, Reuben, Silas, etc.). In the 1800 census, Jonathan, Levy, Samuel, David & David Jr. were listed but no males in the 10-16 bracket where Epenetus would have been had he been is listed. Epenetus eventually moved to Tioga County PA but I am unable to find his father with any certainty. Oddly in a later census he listed Rhode Island as his birth state... NY in another. Any info on his parentage would be appreciated.
