On January 30, 1767, Raymondtown Plantation was granted by the Massachusetts General Court to Capt. William Raymond of Beverly, Massachusetts and his company of soldiers for their service with Sir William Phipps in the 1690 Battle of Quebec. It replaced a 1735 grant called Beverly-Canada (now Weare, New Hampshire) which was ruled invalid in 1741 because of a prior claim by the heirs of John Mason. In 1803, Raymondtown Plantation was incorporated as Raymond. The town of Naples was created with land taken in 1838, the same year the western half of Raymond petitioned the legislature to be set off as a township because of its geographical separation behind Rattlesnake Mountain. The petition failed, but three years later another was accepted. On March 18, 1841, Casco was incorporated as a town.
Farmers found the surface of the town uneven, its hard and rocky soil “tolerably productive.” Outlets of ponds, however, provided Casco with good sites for water powered mills. The town had four sawmills, four gristmills, a shook mill, a barrel stave mill, four shingle factories, a carriage factory and a tannery. In 1832, the Cumberland and Oxford Canal made Sebago Lake a direct trade route to Portland. Steamboat travel commenced on the waterways in the 1840s, carrying tourists and freight. In 1938, Sebago Lake State Park was established, one of the state’s five original state parks.
Casco has no Republican caucus at this time
