On May 21, 1927, New Hampshire’s Secretary of State, Hobart Pillsbury, signed the articles of agreement that established the Historical Society of Cheshire County. The Historical Society of Cheshire County was unique from the beginning because it was, and remains, the only county historical society in New Hampshire. In 1968, the Society became the custodian of the Wyman Tavern, which has been operated ever since by the Society as a period house museum. In December of 1982, the Society moved its archival collection to Rhodes Hall (the former Ball Residence) at Keene State College, and in 1983 a successful endowment drive allowed the Society to hire its first full-time administrator, Alan Rumrill, in 1983. The headquarters of the Society are still at the Ball Mansion and the director is still Alan Rumrill. Today, the Historical Society of Cheshire County has evolved to more than 800 members, five employees, 150 volunteers, and a 13,000 square foot facility that includes a research and genealogy library with more than 300,000 local history items in the collection.
