What drives South River’s History grade

New Jersey towns list more on the Register than most of the country (a typical New Jersey town has 3.7 per 10,000 residents, the U.S. 2.4), so South River’s 1.2 sits below most of its state (35% of New Jersey towns have fewer) while its 2 listings outnumber those of 60% of U.S. towns.

The story

How South River came to be

From Wikipedia’s history of South River.

Read it all →

South River was originally part of East Brunswick Township. Originally referred to as Washington, the community eventually split away, as did Spotswood and Milltown.

From 1683 to 1720, the area was commonly referred to as South River Landing. In 1720, the name Willettstown was adopted after settler Samuel Willett. In 1784, the name was changed to Washington and the area was variously referred to as Washington Village, Washington Woods, and Little Washington. The name was considered at the suggestion of Abraham Barkelew, one of the original settlers in the town. In 1870, the name was changed to South River and on February 28, 1898, South River officially became a borough.

In 1720, Hartshorne Willett, grandson of Sir Thomas Willett, baronet, of England, settled on the west bank of South river, directly in front of where the borough of South River is located, and the place was known as Willettstown until about 1784, when Abraham Barkelew, a pioneer and great admirer of General Washington, renamed the settlement in his honor. The postoffice was first established under the name of Washington, and was so called until it became necessary to change the name on account of a postoffice of the same title in Warren county,
