Pennacook Indians called the area Amoskeag, meaning "good fishing place" -- a reference to the Amoskeag Falls in the Merrimack River. In 1722, John Goffe settled on land beside Cohas Brook, where several years later he built a dam and sawmill. The community was called Old Harry's Town. In 1735, the Province of Massachusetts Bay granted it as Tyngstown to settlers from Massachusetts. A decade following the separation of New Hampshire from Massachusetts, Governor Benning Wentworth in 1751 chartered the town as Derryfield.
