Possible new names included: Upper Middletown, North Middletown, Glenwood, and, the eventual choice, Cromwell, which was put forth by Senator Levi Heaton. In 1850, the town began talks of splitting off into a separate town from Middletown. From that point on, the schools and churches of the Upper Houses (population about 250) were administered (and taxed for) separately from the rest of Middletown. In 1703, Cromwell formed a separate parish from the rest of Middletown due to the inconvenience of crossing the floodplains of the Mattabesset during certain seasons. Settlers first arrived in the area that is now Cromwell in 1651 Cromwell was originally a part of Middletown known as the Upper Houses, likely due to the fact that the Mattabesset River separated it from the rest of Middletown.
