Stockton, New Jersey  Stockton is a borough in Hunterdon County, New Jersey, United States. The borough sits on the Delaware River at the western end of Amwell Valley. As of the 2010 United States Census, the borough's population was 538, reflecting a decline of 22 (-3.9%) from the 560 counted in the 2000 Census, which had in turn declined by 69 (-11.0%) from the 629 counted in the 1990 Census. Stockton was incorporated as a borough by an act of the New Jersey Legislature on April 14, 1898, from portions of Delaware Township. Stockton is located along the Delaware River north of Lambertville. The community was first known as Reading Ferry and later as Howell's Ferry. The name was changed to Centre Bridge Station to match the name of the post office and hamlet on the Pennsylvania side of the river. The name became Stockton with the creation of a railroad station and a local post office in 1851. The community was named in honor of U.S. Senator Robert Field Stockton, who was instrumental in the creation of the Delaware and Raritan Canal. Stockton soon began to develop as an industrious town with mills and quarries sprouting in the area. In 1852 the Belvidere-Delaware Railroad reached town and accelerated its prosperity. The Borough was incorporated in 1898, having been separated from Delaware Township. The Stockton Inn (formerly known as Colligan's Stockton Inn) was established in 1710. The inn's Dog & Deer Tavern first opened in 1796. It is the inn that was the inspiration for Richard Rodgers for his song "There's a Small Hotel (with a wishing well)" sung in the Broadway play "On Your Toes". First built as a private residence it is believed to have been converted to an inn around 1832. Delaware River Mill Society was formed to preserve and promote the buildings and site known as the Prallsville Mills. John Prall Jr., became the owner of the site in 1794 and with his settlement the area became known as Prallsville. The Delaware River Mill Society is a private non-profit organization responsible for the restoration, maintenance, and operation of the historic John Prall Jr. House and the Prallsville Mills Complex, which was listed on the National Register of Historic Places in 1973. The entire property became part of the D & R Canal State Park in 1973. In 1976 when the State of New Jersey was unable to fund the restoration of its newly acquired Prallsville Mills, local citizens formed the Delaware River Mill Society, to "restore, preserve, operate, maintain and interpret" the historic site.
