From "Emigants, Refugees, & Prisoners, Vol. 2, p. 136, by R.W.Davis: "#1311--Jacob FORRY, b. 9 Jun 1757...d.23 Sep 1848." The bio that follows confirms that this is your Jacob. Concern about copyright restrictions prevents quoting more here, but if you contact me personally, I can give you four more generations back from this man.
