History of Westchester County, New York — Passage 112 (part 3)
[J. Thomas Scharf (1886)] The oldest son, Frederick, being heir of his father, became de-visee in tail male of the Manor of Philipsburgh, and tenant for life under his father a will, with remainder in tail male. The Upper Highland Patent of Philips-town, in Putnam County, passed to the second son, Philip, among whose descendants it yet remains. In 1779 all the lands lying in the township of Mount Pleasant, together with all the other lands be-longing to the Manor of Philipsburgh, in consequence of the attainder of Colonel Frederick Philipse for treason to his country during the Revolutionary War, became vested in the State of New York. The act was passed October 22, 1779. On May 12, 1784, the Legislature passed a further act by which it appointed Isaac Stoutenburgh and Philip Van Cortlandt Commissioners of Forfeitures^ for the Southern District of the State, to sell and to dispose of all the real estate in that district that had been forfeited to the State under the above-mentioned act of October 22, 1779. As the township was originally organized on March 7, 1788, Mount Pleasant comprised all that part of the Manor of Philipsburgh lying north of Greenburgh, the north line of which has already been described under the head of " Greenburgh." The north line of the manor and of the original township of Mount PleasAiit commenced at a point on the south shore of the Croton River, two miles above its mouth, and. ran thence by " a direct east line " to the head-waters of the Bronx.
