Before the settlements came, wildlife following antelope and buffalo made their homes in the area. There is also evidence of Arapaho Indians near the Crown Point (Gregory Hill) area. Westminsters’ first remaining settler was Kentucky farmer Pleasant DeSpain, who built his house in 1870 upon 160 acres (near what is now West 76th Avenue and Lowell Street).
