Addison was chartered on October 14, 1761. The town was organized and the first town meeting held March 29, 1784. Addison is exclusively an agricultural township. Though one of the oldest and in a historical point of view one of the most important towns in the State, the only settlement within its limits at all approaching the dignity of a village is a small cluster of houses in the northeastern part of the town, and known as “The Corners.”
