Papers of the family of Socrates Maupin (1809-1871), professor at the University of Virginia, including letters to him, and correspondence of his son, Chapman Maupin (1846-1900), during the Civil War and while studying in Europe. There are also letters and ephemera relating to Chapman Maupin's interest in his Washington forebearers, and deeds, some of which concern other ancestors. The bulk of the papers, 1850-1870, are letters received by Peter Grayson Washington (d. 1872), brother-in-law of Socrates Maupin, primarily while serving as Assistant Secretary of the Treasury, 1853-1857. Most of the letters, many of which are from Congressmen or government officials, are of a routine nature and relate to political patronage, Democratic politics, and the various responsibilities of the Treasury Department. Later letters relate to Washington's work as a claims agent in Washington, D.C., and to his investments in New York City.
