This area was first known as Number 6, one of a line of settlements running between the Merrimack and Connecticut Rivers. Some early settlers were families from Marlborough, Massachusetts, who named it New Marlborough. In 1752 the Masonian Proprietors granted the land to Andrew Todd, who gave it the name Todd's-town. The town was incorporated as Henniker in 1768 by Governor John Wentworth, in honor of Sir John Henniker, a London merchant who had shipping interests in Boston and Portsmouth prior to the Revolution. This town has the distinction of being "the only Henniker on earth."
