What stands out about Northfield’s past
Read from the archive, the National Register and the record. The page puts what stands out first.
European settlers first arrived in Northfield in the early 1700s. Initially, Northfield was incorporated as part of Canterbury when that town was established in 1741. At the time it was a frontier town protected by a garrison fort erected on a hill close to Canterbury Center and commanded by Capt. Jeremiah Clough. Tradition has it that the first settlers of the "north fields" of Canterbury came from the scouts from this fort who patrolled the area in the 1740s.
The north fields of Canterbury prospered. Farming was the principal industry. Additionally, dams along the Winnipesaukee and Merrimack rivers and several brooks powered early sawmills and gristmills. By the 1770s there was a substantial population in the north fields of Canterbury.
In 1780, according to Wikidata. Northfield’s post office opened in 1814, and the first U.S. census counted 606 people here in 1790.
