The southern part of Tuxedo, known as Eagle Valley, was devoted to farming, as were areas just south of Lake Mombasha: Helmsburg and Bramertown were named after early colonial settlers. In the northern part of town, in the area known as Arden, the Greenwood Furnace was established in 1810. During the American Civil War, this forge produced the iron for the famous Parrott rifles, which were built at the West Point Foundry by the Parrott Brothers, then owners of the Greenwood tract.
