Frederick Philipse bought the area that presently constitutes the Town of Ossining from the Sint Sinck Indians in 1685. The Sint Sinck are members of the Wappinger Confederacy, who inhabited the land east of Hudson River between what is now Tarrytown and Croton. His manor extended from Spuyten Duyvil Creek on the border between present-day Manhattan and the Bronx to the Croton River. The last Lord of the Manor, Frederick III, was a Loyalist in the American Revolutionary War who fled to England, so the State of New York confiscated the manor in 1779.
