William Henry Cavendish-Scott-Bentinck, 4th Duke of Portland, PC (24 June 1768 – 27 March 1854), styled Marquess of Titchfield until 1809, was a British politician who served in various positions in the governments of George Canning and Lord Goderich.
He was educated first in Ealing under the tutelage of Samuel Goodenough graduating in 1774, followed by Westminster School (1783). He attended Christ Church, Oxford for two years but did not take a degree.[1] The third Duke, who spared no expense for his heir, sent him to The Hague in 1786 for experience working with the crown's envoy, Sir James Harris. He returned in 1789.[3]
William Henry Cavendish-Scott-Bentinck, 4th Duke of Portland, as a child
Portland was Member of Parliament for Petersfield between 1790 and 1791 and for Buckinghamshire between 1791 and 1809.[3]
He served under his father as a Lord of the Treasury between March and September 1807. He remained out of office until April 1827 when he was appointed Lord Privy Seal by his brother-in-law George Canning.[5] He was sworn of the Privy Council the same year.[5] When Lord Goderich became Prime Minister in August 1827, Portland became Lord President of the Council,[6] an office he retained until the government fell in January 1828. Over time the Duke became less of a staunch Conservative, softening to some of the more liberal stances of Canning.[1]
Portland married Henrietta, eldest daughter and heiress of Major-General John Scott of Fife and his wife Margaret (née Dundas), in London on 4 August 1795. At the time of his marriage he obtained Royal Licence to take the name and arms of Scott in addition to that of Cavendish-Bentinck. They were parents of nine children:[2][7]
Lady Mary Cavendish-Scott-Bentinck (8 July 1809 – 20 July 1874), married Sir William Topham
Death and legacy
The Duchess of Portland died on 24 April 1844.[1] Nearly 10 years later, Portland died at the family seat of Welbeck Abbey, Nottinghamshire, in March 1854, aged 85. Two of their sons predeceased their parents; their eldest dying of a brain lesion and their third son dying of a heart attack.
The duke expressed a desire to be buried in the open churchyard in Bolsover, Derbyshire, near the other family seat at Bolsover Castle. However, he was instead interred in the ancient Cavendish vault, that had previously been unopened for 138 years.[7]
He was succeeded in the dukedom by his second son (but the eldest surviving), William.
