Once known as Charlotteburg, Kinnelon was formed as a borough by an act of the New Jersey Legislature on February 20, 1922, from portions of Pequannock Township, based on the results of a referendum passed on March 21, 1922.[20][21][22] The borough’s name comes from Francis S. Kinney, who purchased 5,000 acres (20 km2) of land in the 1880s for an estate that included Lake Kinnelon, and built St. Hubert’s Chapel in 1886 on an island in the lake.[23][24]

What is now Mount Holly was originally formed as Northampton on November 6, 1688.

The township was renamed Mount Holly as of November 6, 1931, based on the results of a referendum held three days earlier.[22] The township was named for hills covered with holly trees.[23][24] Some areas of today’s Mount Holly were known as Bridgetown.[25][26][27]

Under the terms of an act of the New Jersey Legislature on April 17, 1889, a portion of the old Union Township was incorporated under the name of Boiling Springs Township.[20] The new township took its name from a spring in the community. On March 28, 1894, the Borough of East Rutherford was created, based on the results of a referendum held the previous day, and Boiling Springs Township was dissolved.[20] While there was no change in its borders, the name and form of government were changed.[20][21] The borough was the second formed during the “Boroughitis” phenomenon then sweeping through Bergen County, in which 26 boroughs were formed in the county in 1894 alone.[22]

Originally inhabited during the pre-Columbian era by the Lenape Native American tribe, the region surrounding Waldwick was first explored by Europeans when a Dutch trading expedition landed near there in 1610. With the creation of the Nieuw Amsterdam colony in 1624, the present site of the borough became a Dutch possession along with the rest of northeastern New Jersey. During the period from 1624 to 1664 it was sparsely developed by Dutch settlers, mainly for agricultural purposes. With the annexation of Nieuw Amsterdam by the English in 1664 came a nearly instant increase in immigration to the region and the development of several settlements in and around the present borders of the borough.

Maywood was incorporated as a borough on June 29, 1894, from portions of Midland 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 in the county in 1894 alone.[22] The borough’s name came from the name of a station established in the area by the New Jersey Midland Railroad.[23]

The populated area today known as Hillsdale took form in the mid-to-late 19th century as land speculators, led by David P. Patterson, developed subdivisions to profit from the coming of the Hackensack and New York Railroad (later New Jersey and New York Railroad). The area was incorporated as Hillsdale Township on March 25, 1898, from portions of Washington Township, which had, in turn, been set off from Harrington Township in 1840. Portions of the township were taken on April 30, 1906, to create the township of River Vale. Hillsdale was reincorporated as a borough by an act of the New Jersey Legislature on March 2, 1923, subject to approval which came in a referendum held on April 24, 1923.[20] The borough’s name derives from its location in a “dale among the hills”.[21]

What is now Southampton was originally incorporated as Coaxen Township by an act of the New Jersey Legislature on March 10, 1845, from portions of Northampton Township (now known as Mount Holly Township).
