William Amelius Aubrey de Vere Beauclerk, 10th Duke of St Albans, PC DL (15 April 1840 – 10 May 1898), styled Earl of Burford until 1849, was a British Liberal parliamentarian of the Victorian era.[1]
The Duke served in William Gladstone's government as Captain of the Yeomen of the Guard between 1868 and 1874.[2]
St Albans was the only son of William Beauclerk, 9th Duke of St Albans, and Elizabeth Catherine, daughter of Major General Joseph Gubbins and his wife, Elizabeth (née Bathoe).[3] Maj. Gen. Gubbins was one of the most senior British officers to be posted in New Brunswick, Canada, from 1810 to 1816.
On 13 June 1863, he was appointed Honorary Colonel of the 1st Nottinghamshire (Robin Hood) Rifle Volunteer Corps.[4]
In 1865 he was cited as co-respondent in the Broadwood v Broadwood divorce case. It was accepted that he had committed adultery with Mrs Broadwood but it was shown that she kept a string of other lovers, whilst her husband attended court with his own lover.[5]
St Albans succeeded his father in the dukedom in 1849, aged nine.[3] He later took his seat on the Liberal benches in the House of Lords and served as Captain of the Yeomen of the Guard from 1868 to 1874 in William Ewart Gladstone's first administration. In 1869 he was sworn of the Privy Council, but never returned to active political office, although he accepted appointment as Lord-Lieutenant of Nottinghamshire serving between 1880 and 1898.
St Albans married twice, first to Sybil Mary Grey (28 November 1848 – 7 September 1871, London), daughter of Lt.-Gen. Sir Charles Grey and granddaughter of Charles, 2nd Earl Grey, on 20 June 1867 in London. They had three children:[3]
After the early death of his first wife, he married Grace Bernal-Osborne (26 July 1848, Newtown Anner, Tipperary – 18 November 1926, London),[6] on 3 January 1874 in County Tipperary. She was the granddaughter of London Sephardic Jewish Shakespearian actor turned parliamentarian Ralph Bernal. Her father Ralph Bernal Jr., later Ralph Bernal Osborne, was Secretary of the Admiralty and a parliamentarian. Grace's mother was an Osborne, an Anglo-Irish landed family;
The Duke's second marriage produced five children:
The Duke of St Albans died in May 1898, aged 58, and was succeeded in the dukedom by the only son from his first marriage, Charles, who in turn was succeeded by his younger half-brother Osborne.[3]
He owned a total of 9,000 acres in Lincolnshire and Nottinghamshire.[8]
