The papers of the Malet family span the dates 1808-1937, with most of the papers being dated between 1824 and 1908. The papers consist chiefly of correspondence among members of the Malet family, particularly Sir Charles Warre Malet, Sir Alexander Malet and his wife Lady Marian Dora Malet, Sir Henry Charles Eden Malet, and Sir Edward Baldwin Malet, and their friends and diplomatic associates. Notable correspondents include Queen Sophia of the Netherlands, Sidney Herbert, Lord Clarendon, Lord Napier, Lord Stuart de Rochesay, Lord Brougham, Sir Rennell Rodd, Lord Lyons, Lord Granville and Lord Dufferin. The papers also include printed material, writings, financial papers, clippings, photographs, Lady Marian Dora Malet's diary (1831-1833), Sir Henry Charles Eden Malet's album of illustrations of his service in the Crimean War, and miscellaneous papers. The collection is particularly rich in material concerning 19th-century British diplomacy. The letters of Sir Alexander and Sir Edward Malet thoroughly document British relations with Russia, Portugal, Holland, Austria, Germany, the United States, France, Turkey, Greece, Italy, Belgium, China, and Egypt. The letters and album of Sir Henry Charles Eden Malet in the Malet Family Correspondence Series provide detailed information about the Crimean War, particularly the siege of Sevastopol.
