South Branch is an unincorporated community located within Hillsborough Township in Somerset County, in the U.S. state of New Jersey.[1] The community is named for and is located along the South Branch Raritan River. The South Branch Historic District encompassing the village was listed on the state and national registers of historic places in 1977.
The community goes back to 1750 and was also known as Branchville. It is situated on the South Branch Raritan River near its junction with the Raritan River. The Narticong Tribe of the Lenni Lenape Native Americans lived there and called it "Tucca-Ramma Hocking." It was here that the Dutch who made their way up the Raritan to bargain for land made their deal in exchange for beads, guns, blankets, powder and jugs of rum.
Peter Dumont Vroom, the only Governor of New Jersey from Somerset County, was born in South Branch. Diamond Jim Brady once lived in the house known as the South Branch Hotel, which he purchased for his mistress, Edna Maculey in 1903 paying $68,000 for it and altering it to suit his taste, "Going down to Brady's Farm" became the fashionable thing to do and Anna Held, Flo Ziegfeld, Lillian Russell and other famous personalities of the days were frequent guests.
