Tompkins County, New York
Tompkins County is a county located in the U.S. state of New York. As of the 2010 census, the population was 101,564. The county seat is Ithaca. The name is in honor of Daniel D. Tompkins, who served as Governor of New York and Vice President of the United States.
When counties were established in the British Province of New York in 1683, the present Tompkins County was part of Albany County. This was an enormous county, including the northern part of New York State as well as 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.
