He made leases at different points throughout the manor, but did not sell in fee many farms, though always ready and willing to do so, the whole number of the deeds for the latter on record being only thirteen during the twenty-three years or thereabout which elapsed between his purchase from Mrs. Richbell and his death. Some of these farms, however, were of great extent. He did not establish, as far as now known, any manor courts under his right to do so. The population was so scant, and the manor, like all others in the county, being subject to the judicial provisions of the provincial legislative acts, there was really no occasion for them. He personally attended to all duties and matters connected with his manor and his tenants, never having appointed any steward of the manor. Papers still in existence show that his tenants were in the habit of coming to him for aid and counsel in their most private affairs, especially in the settlement of family disputes, and lie was often called upon to draw their wills Upon the eminence at the head of the [Mamaroneck] Harbor, still called Heathcote Hill, he built a large double brick manor house in the style of that day in England, with all the accompanying offices and outbuildings, including the American addition of negro quarters in accordance with the laws, habits, and customs of the period. Here he lived during the remainder of his life, which terminated on the '28th of February, 1720-1, in his fifty-sixth year. The house stood till some six or seven years before the American Revolution, occupied, however, only by tenants after the death of his widow in 173G. Later it was accidentally destroyed by tire. The present double frame building standing on a portion of the old site was built in 1792 by the late John Peter de Laucey, a grandson of Colonel Heathcote, who had succeeded to the property.
