Northfield was incorporated as a city by an act of the New Jersey Legislature on March 21, 1905, from portions of Egg Harbor Township.[21] A portion of Egg Harbor Township was transferred to Northfield in 1931, and then reverted to Egg Harbor Township in 1933.[22]

Montvale was incorporated as a borough on August 31, 1894, from portions of Orvil Township and Washington Township.[20] The borough was formed during the “Boroughitis” phenomenon then sweeping through Bergen County, in which 26 boroughs were formed in the county in 1894 alone.[21] On February 15, 1896, Montvale acquired part of Orvil Township. In 1906, Montvale added further land from Orvil and Washington townships, and in 1912, Montvale added territory from Upper Saddle River.[20] On May 20, 1959, portions of Montvale were passed to River Vale, and on December 9 and 14, 1965, territories were exchanged between Montvale and Upper Saddle River.[22] The borough’s name is derived from its topography.[23]

Prior to being called West Long Branch, the area had been called Mechanicsville from the 18th century through the Civil War, and then Branchburg in the 1870s. The name West Long Branch appears in the 1889 Wolverton Atlas of Monmouth County, and seems to have derived its name from its proximity to a section of the Shrewsbury River.[21]

The Lenni Lenape Native Americans tilled the soil, hunted in the woods, and fished in the rivers and streams before the Dutch arrived in the early 18th Century. The Dutch settlers, though, left an indelible mark on the area. Early records show that after the English takeover of New Netherland, English Governor Philip Carteret in 1669 granted a real estate speculator named Balthaser De Hart a strip of property which extended east and west from the Hudson River to the Tiena Kill, and north and south from today’s Cresskill into Palisades, New York.[22] It is within these geographical boundaries that lies what is now known as Closter. The first land grant deed for the area today known as Closter was not written until April 13, 1671.[23] The northern half of this tract of land consisting of 1,030 acres (420 ha) (extending from what is Closter Dock Road northward) was purchased by Barent and Resolvert Nagel on April 25, 1710,[24][25] who along with the Vervalen family first settled what is now Closter.

The township is situated in the southernmost part of Morris County bordering both Somerset and Union counties. It is bounded by the Passaic River to the south and west and to the north by the Great Swamp National Wildlife Refuge which covers 7,455 acres (3,017 ha) of land overseen by the United States Fish and Wildlife Service.[22] Refuge lands also lie within neighboring Chatham and Harding townships.

Upper Penns Neck Township was formed on July 10, 1721, when Penn’s Neck Township was subdivided and Lower Penns Neck Township (now Pennsville Township) was also formed. The township was incorporated by an act of the New Jersey Legislature on February 21, 1798, as one of New Jersey’s original group of 104 townships.[21] Portions of the township were taken to form Oldmans Township (February 7, 1881) and Penns Grove borough (March 8, 1894).[21] The township was renamed Carneys Point Township based on the results of a Township meeting held on November 10, 1976, after voters approved a referendum held eight days earlier.[22]

The area that was to become Audubon was initially settled in the late 17th Century by various land owners and was primarily used for farms and mills. In 1695 the land now known as the Borough of Audubon was part of Newton Township. By the early 1700s, the area’s first families were building their homesteads. Today, two of these original farmhouses remain in Audubon. The Low-Stokes-Nicholson house was built c. 1732 by John Low. Simon Breach built his home, known locally as “The Mansion House”, in about 1740. A large addition was built by shipbuilder John Dialogue in c. 1853. Samuel Nicholson Rhodes, a local naturalist and author, owned this farm, which he named “Cedarcroft”, from 1898–1912.[19] It was Mrs. Rhodes who came up with the name for the town. When the Atlantic City Railroad arrived in the 1880s the local farms were subdivided into the smaller communities of Audubon, Cedarcroft and Orston. Residential development began when both Audubon and Orston had train stations built in the 1890s.

What is now Lopatcong Township was created as Phillipsburg Township on March 7, 1851, by an act approved by the New Jersey Legislature from portions of Greenwich Township and Harmony Township. After Phillipsburg was incorporated as an independent municipality on March 8, 1861, the township changed its name to Lopatcong as of March 18, 1863, after the Lopatcong Creek in the area.[19][20]

Pittsgrove Township was formed by Royal charter on December 6, 1769 and was incorporated by an act of the New Jersey Legislature on February 21, 1798, as one of the initial group of 104 townships established in New Jersey. Portions of the township were taken on March 4, 1822, to form Centreville Township (which was restored in 1829 when the township was dissolved), on March 10, 1846, to form Upper Pittsgrove Township and on January 28, 1893, to form Elmer borough.[20] The township was named for William Pitt, 1st Earl of Chatham, a supporter of the colonial cause.[21][22]

Bogota was formed on November 14, 1894, from portions of Ridgefield Township, based on the results of a referendum held that day.[21] The borough was formed during the “Boroughitis” phenomenon then sweeping through Bergen County, in which 26 boroughs were formed during 1894 alone.[22] Portions of Bogota were taken in 1895 to form part of the newly created Township of Teaneck. Bogota was named in honor of the Bogert family, which had been the first European settlers to occupy the area,[23] and may also be a blend of Bogert and Banta, another early family, with an “O” added to ease pronunciation.[24][25][26]
