Sir Watkin Williams-Wynn, 5th Baronet (25 October 1772 – 6 January 1840) was a Welsh landowner and Tory politician who sat in the House of Commons from 1794 to 1840. Biography Williams-Wynn was the son of Sir Watkin Williams-Wynn, 4th Baronet and his second wife, Charlotte, daughter of George Grenville, a former Prime Minister, through whose sister Hester's marriage to William Pitt, 1st Earl of Chatham, Williams-Wynn became cousin to Pitt the Younger. He was educated at Westminster School and Christ Church, Oxford. He succeeded his father in the baronetcy on 29 July 1789. He received Hon. D.C.L. at Oxford in 1793 and was Lord Lieutenant of Merionethshire from 1793 to 1840 and Lord Lieutenant of Denbighshire from 1796 to 1840. In 1819 Williams-Wynn was admitted to Magdalene College, Cambridge and was awarded MA. He declined several offers of a peerage. In later years, Williams-Wynn would return to Westminster School every St. David's Day where he presented all the Welsh boys that he knew with a guinea, and his godson Stapleton Cotton (later Viscount Combermere) with two. Williams-Wynn was elected Member of Parliament (MP) for Beaumaris in 1794 and held the seat to 1796, when following the end of the parliament his uncle Robert Watkin Wynne retired, enabling him to be elected MP for Denbighshire in his place. He held the seat until his death in 1840. He served as Mayor of Oswestry in 1800 and 1831, and of Chester in 1813. In 1800 he served as treasurer of the Salop Infirmary in Shrewsbury. As the largest landowner in North Wales, and controller of many parliamentary seats, he was referred to, at least by himself, as the 'Prince in Wales'. and had a keen interest in military affairs. In 1794 he raised a regiment of fencible cavalry called the "Ancient British Fencibles" and took part in the suppression of the Irish rebellion of 1798, when they were known as "Sir Watkin's lambs" and "a terror of the rebels", acquiring a reputation that he had to defend from charges of cruelty among the Irish. He commanded them until they disbanded in 1800, after Williams-Wynn unsuccessfully requested they be deployed on foreign service. Colonel of the Royal Denbigh Rifles since 1797, he deployed with a militia battalion (3rd Provisional Battalion) largely composed of his own men, to serve under his kinsman the Marquess of Buckingham in France from March to June 1814.
