Sir Henry Drummond Wolff, who died on Sunday last, will long be remembered as a member of the famous Fourth Party. He never reached the position either in Parliamentary or diplomatic life which his undoubted abilities at one time seemed to open to him, but lie played a notable and important part in the House of Commons in conjunction with Lord Randolph Churchill, and will leave a memory as a most resourceful tactician. He was a son of Dr. Joseph Wolff, the famous missionary, who, being converted from Judaism--he was a. Rabbi? took his life in his hand in order to preach Christianity to the Jews and Moham- medans in the East, and of Lady Georgiana Walpole. In spite of his connexion with the audacious Fourth Party, Sir Henry Drummond Wolff served the Conservatives well by founding the Primrose League.

Henry Drummond Charles Wolff was the only child of the Revd Joseph Wolff (a Rabbi's son who converted from Judaism to Christianity) by his first wife Lady Georgiana Mary Walpole (daughter of Horatio Walpole, the Seventh Earl of Orford). He was named after the banker Henry Drummond, who had helped his father financially.

Henry later adopted the surname Drummond-Wolff because he was embarrassed by his father's origins and ideas, and never spoke of him.
At the time of the 1841 census Henry was boarding at a school in Alms House Lane, Wakefield. He went on to Rugby School, which he left in 1846 at the age of sixteen to study foreign languages abroad. He then became a clerk in the Foreign Office in 1849, employed in deciphering despatches. In 1852 he served as attach? to the British legation in Florence, and that is probably where he met the mysterious Adeline Douglas.

In 1853 Henry Drummond-Wolff brought his new wife Adeline back to London when he returned to work at the Foreign Office as private secretary of Lord Malmesbury, the Conservative foreign secretary. Their first child, Horace Henry Drummond-Wolff, was born in London in 1858, and in October of that year Wolff became the private secretary of Sir Edward Bulwer Lytton, the colonial secretary.

Henry married Adeline Douglas on 22 Jan 1853 in British Consulate, Leghorn. Adeline (daughter of Walter Sholto Douglas) was born about 1836; died on 31 Mar 1916 in Hampton Court. [Group Sheet] [Family Chart]

Notes:

Lady Drummond-Wolff (n?e Adeline Douglas) is variously described in the censuses as having been born in Brussels, Scotland, and London. Her census age also varies, making her year of birth anything between 1832 and 1840; in fact, however, not only was she older than her husband (having been born in 1826/7), but her whole existence may have been a deceit, as her alleged father, Walter Sholto Douglas, does not appear to have existed.

In her book Mary Diana Dods, A Gentleman and a Scholar (Baltimore: Johns Hopkins University Press, 1991), Betty T. Bennett puts forward a convincing argument that Walter Sholto Douglas was in fact a woman, Mary Diana Dods, the illegitimate daughter of the 15th Earl of Morton [Ed. unlikely; the Earl died (1774) before Mary was born (1790)] and the close friend of Mary Shelley. Having worked successfully as a writer under the pseudonym David Lyndsay, she appears to have fashioned an entire life for herself as a man, calling herself Walter Sholto Douglas.

Betty Bennett believes that in 1826 Mary Diana Dods rescued the reputation of her unmarried friend, the coquette Isabella Robinson (1809? 1869), by "marrying" her in the persona of Walter Sholto Douglas. Mary Shelley then helped the couple get passports and escape to Paris, where Adeline Douglas (Mrs Kingscote's mother) was born soon afterwards. In Paris Mary Shelley introduced the couple to ?lite Anglo-French society and they mixed with intellectuals such as Stendhal and Fauriel.

Mary Diana Dods died in 1828, leaving her "wife", Isabella Douglas, a respectable widow. Isabella's daughter Adeline Douglas was then only about one year old and may never have known about her background. In 1840 her widowed mother married a clergyman, the Revd William Falconer. She died at the Villa Falconer near Pistoria at the age of 59 on 7 February 1869.

Henry Drummond-Wolff's entry in Who's Who stated that his wife was the daughter of Walter Sholto Douglas, and if Betty T. Bennett's theory is correct, it is possible that he too was deceived about her origins.

Lady Wolff was granted a civil-list pension in 1909 following the death of her husband. At the time of the 1911 census she was the head of the household at 6 Ashburnham Mansions, Chelsea. Her married son, Cecil Drummond Wolff (47), was with her, but not his wife, and they only had one servant. Lady Wolff died at her grace-and-favour apartment at Hampton Court on 31 March 1916, and her age in the death register is (for once) correctly given as 89.
