Cayuga County, New York
Cayuga County is a county in the U.S. state of New York. As of the 2010 census, the population was 80,026. Its county seat is Auburn. The county was named for one of the tribes of Indians in the Iroquois Confederation.
When counties were established in the Province of New York in 1683, the present Cayuga County was part of Albany County. This was an enormous county, including the northern part of the present state of New York and all of the present state of Vermont and, in theory, extending westward to the Pacific Ocean. This county was reduced in size on July 3, 1766 by the creation of Cumberland County, and further on March 16, 1770, by the creation of Gloucester County, both containing territory now in Vermont.
