The Livingston Family Papers spans the eighteenth through the twenty-first centuries, and represents six generations of descendants of John Livingston (1750-1822) of Oak Hill and their relatives by marriage in the Curran, Mulford, Hopkins, and Rogers families. The correspondence, legal and land records, photographs, diaries, scrapbooks, graphics, ephemera, and printed material chronicle the families' business and social lives, travels, interests, and investments. Also documented are their participation in local government, their service in the American Civil War, the Spanish-American War, World War I, and World War II, and their decades of student and alumni involvement with Yale University. Among the papers are deeds, ledgers, indentures, and other business records, which provide detailed accounts of the Livingstons' financial transactions and land holdings, with particular regard to their Oak Hill Iron Mining and Paramount Oil companies, and to their ancestral estate, Oak Hill, all situated along the Hudson River in New York State's Columbia County.
