The Historical Commission of Kennett Township, Chester County, Pennsylvania is appointed by the Township Supervisors to collect, study, and disseminate the history of the Township. The Kennett Township Historical Commission holds about 23 linear feet of archival materials dating from the mid 19th century to the present. Nearly half of the Commission's total holdings are subject files focusing on people, places, organizations, buildings, and events of Kennett Township. The subject files are comprised mainly of secondary-source materials, such as clippings, pamphlets/ephemera, and family genealogies, as well as a small amount of primary-source materials. Another one-third of the Commission's holdings are property research files containing materials compiled during two historic resource surveys in the township. Additionally, the Commission has small collections of oral history recordings, Township records, and papers from the Hannum family.
