Part of the Waldo Patent, it was called the Upper Town of St. Georges Plantation. It was first settled by Scots-Irish settlers from Londonderry in 1736 under the auspices of Brigadier-General Samuel Waldo, its proprietor. Development was hindered, however, by the ongoing French and Indian Wars. In 1753, a blockhouse was built and placed under the command of Captain Thomas Kilpatrick, known by terrified Indians as "Tom-kill-the-devil." War raged across Maine between 1754–1758, and local settlers took refuge in the blockhouse or at another in Cushing.
