The two-story, Federal style house located on the north bank of the Ducktrap River in Lincolnville is all that remains to testify to the micro-empire of George Ulmer, a once and future veteran, politician, and businessman, whose rapid rise to success after the American Revolution and rapid decline in fortunes in the first decade of the nineteenth century nonetheless had a lasting effect on the development of this section of mid-coast Maine. Ulmer, and his brother Philip, were among the first settlers to the region after the Revolution, and over the next twenty years they developed mill seats on the River, built vessels in Ducktrap Harbor, and felled and processed timber from the densely wooded lands back of the coast. After becoming General Henry Knox?s land agent, Ulmer secured important political appointments as Sheriff of Hancock County, Justice of the Peace, and Federal Tax Collector, and in turn served his community as an oft elected representative to the Massachusetts House and Senate. He obtained valuable land commissions for helping Knox legalize land claims, and ran surveys on the lands around Ducktrap. Yet the frontier on which George Ulmer lived and worked was anything but settled, and through a series of misfortunes, and in the face of localized revolt against Knox and his agents, Ulmer?s power, prestige and fortune had all but disappeared by the end of the War of 1812. The George Ulmer House was listed in the National Register of Historic Places for its association with the early settlement of Lincolnville, Northport, and Belmont; for its association with an important local politician, businessman, and military commander; and because of its distinctive Federal style architecture.
