Not every Connecticut town has one and their contact information can be hard to find, but Connecticut's town historians are invaluable resource for any researcher. Many have lived in the towns their entire lives and have researched the town for almost as long. Technically, their job is to answer questions about municipal history, but some work with the local historical society and are willing to answer your general questions. Search town historian and the town name for more information or contact the town clerk.
Be kind... These are volunteers!
