Archives
The Middlesex County Historical Society archives feature a broad spectrum of 18th- to 20th-century public records from the city of Middletown and County of Middlesex. Among the holdings are minutes of selectman's letters, court records, tax lists, town accounts, naturalization records, indentures, and census records.
Our collection of private and business papers from the 1700s to the 1900s is equally wide ranging. Highlights include diaries, journals, account books and correspondence from a diverse selection of local individuals and families; early shipping and maritime records, including custom house records; records of local clubs, organizations and schools; and military records from the Revolutionary War, Civil War and militia.
We also maintain extensive research files on many historical buildings, cemeteries, churches, businesses and local institutions.
