James Brydges, 3rd Duke of Chandos PC (27 December 1731 – 29 September 1789), styled Viscount Wilton from birth until 1744 and Marquess of Carnarvon from 1744 to 1771, was a British peer and politician.
Chandos was the only son of Henry Brydges, 2nd Duke of Chandos, and Lady Mary Bruce, daughter of Charles Bruce, 3rd Earl of Ailesbury.
Chandos was Member of Parliament for Winchester from 1754 to 1761 and for Radnorshire between 1761 and 1768. He succeeded in the dukedom upon the death of his father on 28 November 1771.
Marriages and children
Chandos's first marriage was to Margaret Nicol (1736–1768), daughter of John Nicol, on 22 March 1753. Margaret was the owner of a famous portrait of Shakespeare, which came to be known as the Chandos portrait following the marriage. Following the death of his first wife he married Anne Eliza Gamon, daughter of Richard Gamon, on 21 June 1777. His second marriage produced the only child to survive to adulthood — Lady Anne Elizabeth Brydges (died 1836), who married Richard Temple-Grenville, 1st Duke of Buckingham and Chandos. Chandos died in September 1789, aged 57, when the Dukedom became extinct. He was buried in St Lawrence Whitchurch in Canons Park, London.
