The Pulteney Association was a small group of British investors who in 1792 purchased a large portion of the Western New York land tract known as the Phelps and Gorham Purchase. The Pulteney Associates were Sir William Pulteney, 5th Baronet (1729–1805), a Scottish lawyer who owned nine-twelfths; William Hornby, former Governor of Bombay, who owned two-twelfths; and Patrick Colquhoun, a Scottish merchant with a one-twelfth share. Some of their heirs owned land in western New York into the 1920s, with the last parcel of The Pulteney Association property, 10 acres, being sold in December 1926.
