Searching for Records in Delaware County, NY

Delaware County is located in south-central New York and is part of the Catskill Mountain region. The county gets its name from the Delaware River, which constitutes its western border and separates the county from Pennsylvania. The east and west branch of the Delaware run through the center of the county.

Delaware is bordered in the north by Otsego and Schoharie counties, in the east by Greene County, and the south by Ulster and Sullivan counties. Though one of the largest by area, Delaware is one of the less populated counties in New York, with a population of 47,980 (according to the 2010 census.) The county seat lies in central Delaware in the town of Delhi.
