The St. Mary's County Historical Society seeks to preserve and share the history of St. Mary's County, Maryland, known as the "Mother County of Maryland." Historic Tudor Hall, once visited by George Washington, houses the society's museum collection and research center; while the Old Jail, built in 1858, is another museum exhibit venue. The research center includes access to maps, surveys, business records, water district and government records, club and organization minutes, school records, diaries, marriage licenses, music, ships' lists, newspaper clippings, family genealogies, letters, almanacs, telephone directories, postcards, family movies, friendship cards, military records, church records, paintings, Bibles, and other books.
The society offers exhibits and historical outreach presentations. Please confirm dates of visitation.
