Anne Scott Jefferson, (October 1, 1755 - July 8, 1828)[1] was Thomas Jefferson's youngest sister (a twin to Randolph Jefferson). She married Hastings Marks in October 1787. According to her great-niece Virginia Jefferson Randolph Trist, Anne and Hastings Marks had one son, Valentine, who married a "Miss Brockenborough of Port Royal." Valentine and his wife reportedly "left 2 daughters Sarah & Lizze Brockenborough (who lived in Port Royal) and a son Randolph."[2]  Researchers have discovered this information to be incorrect; Anne is not known to have had any children. (The Valentine mentioned is most likely Valentine Peyton, son of Craven Peyton and Jane Jefferson Lewis, who married Elizabeth Brockenbrough.)[3]  Ann (or Anna) Scott Marks (called "Aunt Marks" by Thomas Jefferson's children and grandchildren) came to live at Monticello with her brother after her husband's death in 1811; she died at Monticello in 1828.  The location of her grave is not known.
