The West Patent, dated February 14, 1701, to Robert Walter and nine other patentees, included all of the large angle between Philipseburgh and Cortlandt Manors, and stretched eastwardly to the Bryam River and the Town of Bedford. It contained five thousand acres of improvable land. The Middle Patent, dated February 17, 1701, to Caleb Heathcote and twelve others, extended from the West Patent to the Mianus River, and had fifteen hundred acres of improvable land. The East Patent, the largest of the three, embracing sixty-two hundred acres of improvable land, was granted on the 20th of March, 1701, to R. Walter and ten others, and covered much of the northeastern section of the county. In the purchases consolidated in these three patents Heathcote was the original mover, but had the co-operation of several other active parties, notably Robert Walter and Joseph Horton. Heathcote, with a view to protecting his individual interests already acquired in the deed from Mrs. Richbell (which transferred to him such rights as she and her husband had previously possessed "northward twenty miles into the woods"), had a proviso inserted in each of the new patent deeds reserving to himself any lands possibly included in these purchases whereof he might already be the owner. The first of the purchases leading up to the three patents was made by him personally, October 10, 1696 (seven days after the procurement of his license from Governor Fletcher), from Pathunck, Wampus, Cohawney, and five other Indians. This is known as " Wampus's Land Deed," or the " North Castle Indian Deed," and was " for and in consideration of 100 pounds good and lawful money of New York." Among the names of Indian chiefs participating in the sales of the northern-central Westchester lands to Heathcote and his associates is the familiar one of Katonah.
