Dummerston was part of the Equivalent Lands—several large sections of land given to settlers in the early eighteenth century. It lies on a tract given to the Connecticut Colony about 1715 by the Province of Massachusetts Bay as compensation for land mistakenly awarded by the latter to its settlers. In 1716, the town was auctioned to a consortium (which included William Dummer, lieutenant governor of Massachusetts), and named Dummerston. On December 26, 1753, the town was chartered as a New Hampshire grant and renamed Fulham by Governor Benning Wentworth. But when the grant was renegotiated, it reverted to Dummerston.
