Formally incorporated in 1835, the Town of Bloomfield is rooted in a 1640 settlement known as the Messenger Farms located at the eastern end of what is now Park Avenue. Originally part of Windsor, the settlement slowly grew to over 900 persons by the time of its incorporation. What led to the formal incorporation of Bloomfield was the founding of a new parish called Wintonbury in 1736 (a composite of the names of the three founding towns: Windsor, Farrnington, and Simsbury).
