1. Thomas Mann Randolph (1768–1828) was the son of Thomas Mann Randolph and Anne Cary Randolph and the son-in-law of Thomas Jefferson. Educated at the University of Edinburgh, he returned to Virginia in 1788 and helped run Monticello during Jefferson’s absences. He served as an Albemarle County justice of the peace, a captain in the Virginia militia, and, from 1803 to 1807, a member of Congress. On 3 Mar. 1813 the Senate confirmed JM’s nomination of Randolph to the Twentieth Regiment of Infantry as a colonel. He participated in the campaign against Montreal under Maj. Gen. James Wilkinson but returned to Virginia when the campaign was abandoned and resigned his commission in 1814. After the war, he continued his unsuccessful efforts to make his large farms profitable and resumed his political pursuits, serving as governor of Virginia, 1819–22, and as a member of the Virginia House of Delegates, 1819–20 and 1823–25 (George Green Shackelford, ed., Collected Papers to Commemorate Fifty Years of the Monticello Association of the Descendants of Thomas Jefferson [2 vols.; Princeton, N.J., 1965–84], 1:45–66; Senate Exec.
