About Us

The Washington County Historical Society administers several sites—the Francis J. LeMoyne House, the LeMoyne Crematory, the Norma K. Grimes Research Library and the Washington County Frontier History Center.  The Historical Society utilizes these sites to educate the public through offering tours, special events, outreach programs and research services.  As the repository for Washington County heritage, the Historical Society maintains an extensive collection of documents and artifacts.



The Washington County Historical Society endeavors to collect and preserve Washington County's history, to increase awareness and to educate the public about the history and national significance of Washington County.  It is also the responsibility of the Historical Society to preserve the sites under its administration.
