Township of Union: https://www.uniontownship.com/
Union is a township in Union County, New Jersey, United States. In the 18th century, the area that is now Union was then called Connecticut Farms.
Settled in 1667, Union was the third English speaking settlement in New Jersey after Elizabeth and Newark, with the area that is now Union then called Connecticut Farms.
Union Township was the site of the Battle of Connecticut Farms, one of the last battles between British and American forces during the American Revolutionary War. On June 6, 1780, British troops, led by Hessian General Wilhelm von Knyphausen, boarded boats on Staten Island bound for Elizabeth, New Jersey. At midnight, 5,000 troops started to land. They expected the Continental Army to give little resistance, believing that they were tired of the war and were poorly fed and paid. They also expected the citizens of New Jersey to welcome them. They were wrong on both counts and were unable to make their way to and through the Hobart Gap.
The Township of Union is located on the northern-central edge of Union County and is bordered by eight municipalities: Hillside to the east, Elizabeth to the southeast, Roselle Park and Kenilworth to the south and Springfield Township to the west. Northwest of the township lies Millburn, to the north lies Maplewood and to the northeast lies Irvington, all in Essex County.
According to the United States Census Bureau, Union township had a total area of 9.092 square miles (23.548 km2), including 9.071 square miles (23.494 km2) of land and 0.021 square miles (0.055 km2) of water (0.23%).
