North Caldwell was incorporated by an act of the New Jersey Legislature on March 31, 1898, from portions of Caldwell Township (now known as Fairfield Township).[20] The borough derives its name from Presbyterian minister James Caldwell.[21][22]

In 1888, Henry J. Appert, a Swiss immigrant, drained a bog for the cultivation of onions and celery. The business—Allendale Produce Gardens, or the “celery farm” to locals—supplied wholesale markets and Campbell Soup Company. Allendale was formed on November 8, 1894, from portions of Franklin Township (remainder now Wyckoff), Hohokus Township (remainder now Mahwah) and Orvil Township (remainder now Waldwick).[20][21] 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.[22] The borough was named for Joseph Warner Allen, a surveyor for the Erie Railroad.[23]

Linwood was originally incorporated as a borough by an act of the New Jersey Legislature on February 20, 1889, from portions of Egg Harbor Township, based on the results of a referendum held the previous day. Linwood was reincorporated as a city on April 27, 1931.[20] The area had been called Leedsville until 1880, when a post office was being established. The United States Postal Service insisted that the name had to be changed as it conflicted with an existing post office elsewhere in the state. Among the names proposed and considered by local residents were “Brinola”, “Geneva”, “Pearville” and “Viola”, with “Linwood” ultimately chosen.[21]

The Borough of Stratford was created on February 13, 1925, from portions of Clementon Township, one of seven municipalities created from the now-defunct township.[19] The borough was named for Stratford-upon-Avon, England, by the owners of the Rural Land Improvement Company that developed the area in the 1880s.[20][21]

Midland Park was incorporated as a borough on September 6, 1894, at the height of the “Boroughitis” craze then sweeping through Bergen County that led to the creation of over two dozen new municipalities in the county in that one year alone. The new borough consisted of portions of both Franklin Township and Ridgewood Township. The borough expanded in April 1920 by adding another part of Franklin Township. In a referendum held on June 9, 1931, Midland Park acquired additional land from Wyckoff (which until 1926 had been known as Franklin Township).[21][22] The borough says that Midland Park was named after the New Jersey Midland Railway, which operated the railroad passing through the area of the borough in the 1870s,[22] though elsewhere the name is said to be based on being situated “amid Bergen hills”.[23]
