Lunenburg was granted by Benning Wentworth, the royal governor of New Hampshire, on July 5, 1763 to David Page and 68 other people. It is widely believed that David Page named the town, which stems from one of the titles for Prince Karl Wilhelm Ferdinand of Brunswick-Lunenburg. Lunenburg was the home of Vermont State Representative Adino Nye Bell. Lunenburg is also believed to have inspired the Robert Frost poem "The Mountain", which takes place in a town called Lunenburg.
