The Dutch first explored Hillsborough and the surrounding area in the
middle 17th century. At that time, the Unami Indians, who were a part of the
Lenapi Tribe, occupied the area. Hillsborough received its Charter on May
29, 1771, and officially became Hillsborough Township. Before that date it
was known as the "Westering Precinct of Somerset County." Hillsborough is a
collection of small villages, including Belle Mead, Blackwells Mills,
Flagtown, Neshanic and South Branch. It was a rural community throughout
the late 19th century and most of the 20th century.
Between 1970 and 1988, the township’s population more than doubled.
