The town was first settled in 1793 by Ezekiel Lewis, an English Loyalist supporter who was originally from Marlborough, New Hampshire. He named his location Lewis Falls and after 9 years, Captain Lewis sold his lot and moved a short distance away. The land was purchased by William Lamoure, a merchant from St-Armand who then sold it to Lazare Letourneau who in turn sold it to Hezekiah Robinson in 1822. Robinson immediately renamed Lewis Falls to Waterloo after the famous battle in which Napoleon Bonaparte was defeated. The name Waterloo was suggested by his father-in-law, Judge Knowlton. Hezekiah Robinson built "The Old Stone Store" in 1829 at the corner of Main Street and Ellis.He donated the land for the first Church of England built in 1843 and his widow donated Robinson Park in 1868 plus the land for the French school. In 1843, Waterloo became the county seat replacing Frost Village.
