This early mill and farming community incorporated from Branford in 1831. The year prior, Maltby Fowler had opened a button-making shop. Its success along with the inventiveness of his six sons—who devised a range of machines to produce such things as screws, embossed silk, pins, and horseshoe nails—saw the rise of new manufactures along the town's Farm River. By the early 1900s, North Branford's abundant supply of trap rock, a material used for making roadways, made quarrying a growth industry. Today, the town's manufacturing sector is concentrated in electronics and electronic components.
