It was first settled in 1770 by Captain Joseph Dingley and Dominicus Jordan of Cape Elizabeth, although most families arrived after the Revolutionary War. It was on the stage route to Bridgton. On June 21, 1803, the Raymondtown Plantation was incorporated as Raymond, named in honor of Captain Raymond. In 1829, land was annexed to help form the new town of Naples, and in 1841, Casco was set off and incorporated as a town.
