I don't know if this is your Jacob FELT or not, but I found this in my notes:
Jacob Felt, son of Aaron Felt and his first wife, Tabitha Upton of Temple, Hillsboro, NH
Born: 16 May 1786, Tample, NH [Felt family Gen.] Marriage: Betsy NEAGLES [Internet "Felt Family Gen."] Betsy was the daughter of Michael NEAGLES and Sarah LeBOSQUET [DAR Lineage Boos, Mrs. Anna Felt Clark, #47823]
I don't know if Jacob went to New York, but his sister Abiatha (my ancestor) and her husband Jesse BRAMAN along with Abiatha's brother, Aaron, all went to Essex Co., NY.
The only Felt listed in the 1790 New York census (that I can find) is: Jonathan FELT, 1 male +16; 2 females, in Easton, Albany, NY
