Originally a part of Rochester, this town was long known as Three Ponds or Milton Mills. Located along the Maine border on the Salmon River, it was the location of several mills, and the scene of early manufacturing. The name Milton may have come from a relative of the Wentworth Governors, William Fitzwilliam, Earl of Fitzwilliam and Viscount Milton. Milton is home to Mount Teneriffe, among the earliest of New Hampshire's mountains to be named, and so named in honor of the volcano on the Canary Islands.
