The Union Township Historical Society owns, operates, and maintains the Caldwell Parsonage Museum. Once the home of James and Hannah Caldwell and their nine children, the building is listed on the National and State Registers of Historic Places.
The Caldwell Parsonage was the site of the Battle of Connecticut Farms and the shooting of Hannah Caldwell.
Towns and streets throughout the state are named after the Caldwells. In 1998, the Township of Union honored Hannah Caldwell by dedicating Hannah Caldwell Elementary School to her memory.
