Catherine Hannah Charlotte Elliot was born and raised in Yorkshire, England. In 1856, she married as his second wife Sir George Jackson, a diplomat and civil servant, and became Lady Jackson. After her husband's death in 1861, she compiled and edited his private diaries and papers. She issued The Diaries and Letters of Sir George Jackson from the Peace of Amiens to the Battle of Talavera (1872) and The Bath Archives: a further Selection from the Diaries and Letters of Sir George Jackson (1873). Lady Jackson studied a variety of old French memoirs, and went on to write several interesting, though sometimes inaccurate, books on French royal history and aristocratic society. These included Old Paris: Its Court and Literary Salons (1878), The Old Regime: Court Salons and Theatres (1880), The French Court and Society, Reign of Louis XVI and the First Empire (1881), The Court of the Tuileries from the Restoration to the Flight of Louis Philippe (1883), The Court of France in the Sixteenth Century (1885) and The Last of the Valois and the Accession of Henry of Navarre (1888). She often wrote about art, especially Western painting, in her books.
