Wellsville was the location of encampments for thousands of years, including the Lamoka and Brewerton cultures. The latest native people, the Seneca, named Wellsville "Gistaguat", according to a map produced in 1771 by Guy Johnson, as the official map of New York state at the time, for then-Governor William Tryon. The Seneca referred to the Wellsville area as "the Pigeon Woods" and held annual festivals and encampments there to take advantage of the passenger pigeon (see memoirs of Captain Horatio Jones). At the time, passenger pigeons filled the skies by the millions, and the tribes and bands came to the Wellsville area from all over western New York and northern Pennsylvania to Gistaquat to harvest the pigeons by the thousands.
