The story

How Mannington Township came to be

From Wikipedia’s history of Mannington Township.

Read it all →

Mannington Township was first mentioned on May 12, 1701. It had been previously known as East Fenwick Township, which was mentioned on September 3, 1679, though the details of its incorporation are unknown. The township was incorporated by New Jersey Legislature's Township Act of 1798 on February 21, 1798, as one of New Jersey's original group of 104 townships. A portion of the township was taken in 1878 and annexed by Quinton Township. The township's name derives from the Lenape deity, variously spelled as Maneto or Manito.

Among the oldest buildings are Barrett's Plantation House and the Salem County Insane Asylum.
