In 1695, Thomas Powell bought about 10,000 acres (40 km2) from local Indian tribes, including the Marsapeque, Matinecoc, and Sacatogue, for 140 English pounds. This land, which includes modern Bethpage, East Farmingdale, Farmingdale, Old Bethpage, Plainedge, Plainview, South Farmingdale, and part of Melville, is known as the Bethpage Purchase and is approximately 3.5 miles (5.6 km) east to west and 5 miles (8.0 km) north to south.
