Finns Point is a small strategic promontory in Pennsville Township, Salem County, New Jersey, and New Castle County, Delaware, located at the southwest corner of the New Jersey peninsula, on the east bank of the Delaware River near its mouth on Delaware Bay. Due to a geographic curiosity, part of the promontory is actually enclosed within the state of Delaware's border, due to tidal flow and the manner in which the borders between New Jersey and Delaware were first laid out. Therefore, this portion of Finns Point is an exclave of Delaware, cut off from the rest of the state by Delaware Bay. The area is about 10 miles (16 km) south of the city of Wilmington, and directly across the Delaware River from the New Castle area, and the Delaware River entrance to the Chesapeake & Delaware Canal. Pea Patch Island, part of the state of Delaware, sits in the channel of the river facing the promontory.
At the time of European colonization in the 17th century the Delaware River was known as the South River and the Salem River was known as Varkens Kill, or Hogg Creek.
Tradition holds that a settlement was first planted by Finns as part of the colony of New Sweden in 1638. among them, the family of Anders Sinicka, whose surname has many variations. This is recalled in the name of the road running along the shore south of the Port of Salem, Sinnicksons Landing Road. which bears the name of the a prominent Salem County family, including Thomas Sinnickson and his descendants.
