Aldred Lumley, 10th Earl of Scarbrough

Major-General Aldred Frederick George Beresford Lumley, 10th Earl of Scarbrough, KG, GBE, KCB, GStJ (16 November 1857 – 4 March 1945) was a British peer and soldier. His first name is sometimes rendered as Alfred, not Aldred.

Lumley was the son of Richard Lumley, 9th Earl of Scarbrough and was educated at Eton. He was Lord Lieutenant of the West Riding of Yorkshire from 1892 to 1904 and commanded the 7th Hussars, the Yorkshire Dragoons and the Yorkshire Mounted Brigade during the Boer War in 1900 and afterwards became an aide-de-camp to King Edward VII in 1902. He was Director-General of the Territorial Force until his retirement in 1921.

On 8 April 1899, Scarbrough married Lucy Cecilia Dunn-Gardner (d. 24 November 1931), widow of Col. Robert Ashton (d. 1898). His wife brought a stepson and stepdaughter to their marriage, and gave birth to a single daughter Lady Serena Lumley. Lucy was the daughter of Cecil Dunn-Gardner.

The Countess's father was probably Cecil Dunn-Gardner (b. 1827, possibly d. by 1880), formerly of the 13th light Dragoons. If the identification is correct, he was the third surviving son of the brewer John Margetts (d. 1842) and his bigamous wife Sarah Dunn-Gardner, Marchioness Townshend, and the younger brother of John Dunn Gardner MP.

Scarbrough's stepdaughter Dorothy Violet Ashton (1885–1956) married in 1914 Lord Gerald Wellesley (1885–1972), who succeeded his nephew as Duke in 1943. The marriage was not a great success, but produced a son and daughter. The son is the present Duke of Wellington (b. 1915), still alive, in his nineties.

Scarbrough's own daughter Lady Serena Lumley married 1923 the Hon. Robert James, and later refused the marriage proposal of her brother-in-law, by then Duke of Wellington. Her elder daughter Ursula James married David Allan Bethell, 5th Baron Westbury (1922–2001); their son Richard is the present 6th Baron.

Scarbrough was appointed Knight Grand Cross of the Order of the British Empire (GBE) shortly before his retirement from the Territorial Force in 1921 for his military service.
