Wyoming County, New York
Wyoming County is a county in the U.S. state of New York in the state's western area. As of the 2010 census, the population was 42,155. The county seat is Warsaw. The name is modified from a Lenape (Delaware) Indian word meaning "broad bottom lands". Wyoming County was formed from Genesee County in 1841.
As with the rest of Western New York, Wyoming County was part of disputed territory throughout the 17th and 18th centuries, claimed by the Massachusetts Bay Colony, Connecticut Colony, Pennsylvania Colony, New York Colony, and (to a lesser extent) New France. New York's claims were not recognized until the Treaty of Hartford was ratified in 1786 and were not actively asserted until the Holland Purchase.
