Delaware County is a county located in the US state of New York. As of 2010 the population was 47,980. The county seat is Delhi. The county is named after the Delaware River, which was named in honor of Thomas West, 3rd Baron De La Warr, appointed governor of Virginia in 1609.
When counties were established in New York State in 1683, the present area of Delaware County was divided between Albany and Ulster Counties.
Albany County 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. On March 12, 1772, what was left of Albany County was split into three parts, one remaining under the name Albany County. One of the other pieces, Tryon County, contained the western portion (and thus, since no western boundary was specified, theoretically still extended west to the Pacific). The eastern boundary of Tryon County was approximately five miles west of the present city of Schenectady, and the county included the western part of the Adirondack Mountains and the area west of the West Branch of the Delaware River. The area then designated as Tryon County now includes 37 counties of New York State. The county was named for William Tryon, colonial governor of New York.
