# Franklin Township, Somerset County, New Jersey

Franklin Township is a township in Somerset County, in the U.S. state of New Jersey. It is centrally located in the Raritan Valley region within the New York Metropolitan Area. As of the 2020 United States census, the township's population was 68,364, an increase of 6,064 (+9.7%) from the 2010 census count of 62,300, which in turn reflected an increase of 11,397 (+22.4%) from the 50,903 counted in the 2000 census. The township was the state's 19th most-populous municipality in 2020, after being ranked 22nd in 2010.
Traditionally a farming community, it has become a fast-growing suburb with massive development in the late 20th and early 21st centuries, fostering a diverse blend of races, religions, and cultures. In 2008, Franklin Township ranked #5 on Money magazine's list of America's Top 100 Best Places to Live.
What is now Franklin Township was originally formed circa 1745 as Eastern precinct. Franklin Township was incorporated on February 21, 1798, as one of New Jersey's initial group of 104 townships by an act of the New Jersey Legislature. Portions of the township were taken to form South Bound Brook (formed within Township, became an independent municipality as of April 11, 1907) and East Millstone (formed on February 18, 1873, and returned to Franklin Township on December 31, 1949).

## History

It has been unclear if the township was named for founding father Benjamin Franklin or for his illegitimate son William Franklin, a Loyalist and the last Royal Governor of New Jersey (from 1763 to 1776). In 2000, after considering the evidence set forth by William B. Brahms in his books Images of America: Franklin Township (1997) and Franklin Township, Somerset County, NJ: A History, and The Case for William Franklin and The Case for Benjamin Franklin, the Township Council chose the theory that the township was indeed named for Benjamin Franklin.
Franklin Township was very much a part of Revolutionary War history and the scene of many raiding parties along Route 27, then known as the King's Highway. Two British generals, Cornwallis and DeHeister, tried to lure General George Washington and his Continental Army into battle on the plains of Middlebush and East Millstone. Washington, however, kept his troops at Chimney Rock, just north of Franklin, until the British withdrew. Several of the prosperous Middlebush farms were destroyed by the British soldiers during their retreat. In 1777, near the mill on the Millstone River at Weston, the Continental Army and local militia engaged and successfully drove off a British foraging party of about 600 troops, sent out of New Brunswick by General Cornwallis. On November 2, 1783, Washington composed his farewell address to the army while staying at Rockingham near Rocky Hill.
The construction of the Delaware and Raritan Canal in the 1830s, stretching 22 miles (35 km) to connect New York City and Philadelphia, led to significant growth in the township, with as much as 200,000 tons of goods shipped on barges using the canal by the 1860s. The rise of shipping commercial goods using railroads led to a substantial decline in canal traffic. The area has been restored as the Delaware and Raritan Canal State Park
The Van Wickle House, located next to the Delaware and Raritan Canal in the Somerset section of the township, in between New Brunswick and South Bound Brook, was built in 1722 by Dutch settlers and is now owned by Franklin Township and leased by the Meadows Foundation. Set back behind Easton Avenue, the home adjoins the Rutgers Preparatory School and a Revolutionary War-era graveyard.
Passenger and freight railroad service was available in Franklin Township during the later half of the 19th century via the Millstone and New Brunswick Railroad (M&NB) which opened in 1854. The railroad was built and operated by the Pennsylvania Railroad (PRR), from a junction with the PRR mainline at Jersey Avenue in New Brunswick to East Millstone. The M&NB is now known as the Conrail Millstone Secondary Branch. The branch line was still operated by Conrail up to just west of Clyde Road in Somerset for a time, serving local industry in the industrial section of Somerset. As of 2011, Hermann Warehouse Corp re-located out of the Clyde Road facility and there has not been rail service into that building since then. A bumper was placed east of the Somerset Road/Route 27 crossing, with Clyde Road, Veronica Avenue and Route 27 crossings currently out of service. Jersey Avenue/Route 91 remains the sole active crossing on the line.
In 1922, the infamous Hall-Mills Murder took place in Franklin Township, in the area adjacent to New Brunswick known as Somerset.

## Government
### Local government

The Township of Franklin is chartered under the Faulkner Act, formally known as the Optional Municipal Charter Law, within the Council-Manager, Plan D. The township is one of 42 municipalities (of the 564) statewide that use this form of government. The Township Council is comprised of nine members, including one from each of the five wards, three elected from the township at-large, and the mayor. The mayor is the Chief Legislative Officer of the township and is directly elected from the township at-large to serve a four-year term. The Township Manager is the chief executive officer overseeing the township's daily operations and is hired by and serves at the pleasure of the Township Council. Councilmembers are chosen for a four-year term in partisan elections held at the June Primary and November General Elections in odd-numbered years, with the five ward seats coming up for election together and the mayoral and at-large seats up for election two years later.
As of 2022, the Mayor of Franklin Township is Democrat Phillip Kramer, whose term of office ends December 31, 2023. Members of the Township Council are Deputy Mayor Crystal Pruitt (D; At-Large, 2023), Sivaraman Anbarasan (D; At-Large, 2023), Kimberly Francois (D; At-Large, 2023), Charles Onyejiaka (D; 3rd Ward, 2025), Ed Potosnak (D; 1st Ward, 2025), Shepa Uddin (D; 2nd Ward, 2025), James Vassanella (D; 5th Ward, 2025) and Carl R.A. Wright (D; 4th Ward, 2025).
In the November 2015 general election, Phillip Kramer became the first Democrat directly elected as mayor in the township's history, resulting in the mayor and entire council being from the Democratic Party. This marked a transition that started in 1995, when the council was controlled 8 to 1 by the Republican Party. In January 2016, the Township Council selected Charles Onyejiaka from a list of three candidates nominated by the Democratic municipal committee to fill the Third Ward seat expiring in December 2017 that was vacated by Philip Kramer when he took office as mayor; Onyejiaka will serve on an interim basis until the November 2016 general election, when voters will select a candidate to fill the one-year balance of the term of office.
In January 2015, the Township Council chose Chris Kelly from among three candidates offered by the Republican municipal committee to fill the vacant seat of Brian D. Levine, who had resigned from his council seat to take office on the Somerset County Board of Chosen Freeholders.
In 1998, the township approved a referendum by a better than 2–1 margin to raise property taxes by 3 cents per $100 of assessed valuation, with the money to be used to preserve open space.

Franklin Township was to house the northern end of the Somerset Freeway at I-287 back in 1964 until it was later proposed to end in Piscataway. An additional spur, Interstate 695, was also proposed as part of the project. This road was to complete Interstate 95 at the proposed southern end in Hopewell Township at I-95 and I-295. However the entire project was ultimately cancelled in 1982.
