Cornelia Jefferson Randolph (1799–1871) was born at Monticello, the fifth child of Thomas Mann Randolph and TJ’s daughter Martha Jefferson Randolph. Like her siblings, Randolph spent much of her time at Monticello and accompanied her grandfather at least once to Poplar Forest, where she occupied herself with her studies. She learned mechanical drawing from TJ and practiced by reproducing architectural plans made for the University of Virginia. Randolph lived at Tufton and then Edgehill, the homes of her eldest brother, Thomas Jefferson Randolph. She taught drawing, painting, and sculpture at the school the family operated at Edgehill during the 1830s and 1840s. Randolph translated and edited The Parlor Gardener: A Treatise on the House Culture of Ornamental Plants. Translated from the French and Adapted to American Use (Boston, 1861). After the Civil War she moved to Alexandria to live with two of her sisters at the home of her niece Martha Jefferson Trist Burke, where she died unmarried. Randolph was buried in the family graveyard at Monticello (Shackelford, Descendants description begins George Green Shackelford, ed., Collected Papers to Commemorate Fifty Years of the Monticello Association of the Descendants of Thomas Jefferson, 1965 description ends , 1:147–53, 253; TJ to Martha Jefferson Randolph, 31 Aug. 1817; Randolph’s drawing of Pavilion X at the University of Virginia [ViU] and her commonplace book [DLC: DLC: TJ Papers, ser. 6]; Alexandria Gazette, 27 Feb. 1871).

Randolph was visiting the Bankheads at their Port Royal estate in Caroline County (Elizabeth Trist to Catharine Wistar Bache, 7 May 1811 [PPAmP: Catharine Wistar Bache Papers]).
