During the second and third quarters of the 18th century, most of the Mohawks in the Province of New York lived along the Mohawk River at Canajoharie. A few lived at Schoharie, and the rest lived about 30 miles downstream at the Tionondorage Castle, also called Fort Hunter. These two major settlements were traditionally called the Upper Castle and the Lower Castle. The Lower Castle was almost contiguous with Sir Peter Warren's Warrensbush. Sir William Johnson, the British Superintendent of Indian Affairs, built his first house on the north bank of the Mohawk River almost opposite Warrensbush and established the settlement of Johnstown.
