The Clayton Historical Society was founded in 1974 to "research, collect, record, preserve, display, borrow, share, and interpret local history information and memorabilia, and to promote understanding of Clayton origins and development."
Its volunteers finance, maintain and operate the non-profit Clayton Historical Museum as the major local history resource for students, writers, genealogical researchers, city and county needs, developers, businesses, new residents, and visitors including many from other states and countries.
It locates, records, inventories, publicizes and marks historic sites, buildings and natural features making recommendations.
In addition to maintaining regular museum hours, the Society hosts student classes and special tours and opens the Museum upon request. The Society has developed a "twinning" bond with Joel Clayton's birth town, Bugsworth, England, and the town he founded.
