Sir Watkin Williams-Wynn, 4th Baronet (23 September 1749 – 24 July 1789) was a Welsh landowner, politician and patron of the arts. The Williams-Wynn baronets had been begun in 1688 by the politician Sir William Williams, 1st Baronet, but had inherited, in the time of the 3rd baronet, Sir Watkin's father, the estates of the Wynn baronets, and changed their name to reflect this. Early life Williams-Wynn was the eldest son of the second marriage of his father, Sir Watkin Williams-Wynn, 3rd Baronet, to Frances Shackerley of Cheshire. He was a baby when his father was killed by a fall from his horse while out hunting, and he inherited the extensive Wynnstay estates, the largest in North Wales. These straddled at least five Welsh counties and extended into Shropshire in England, and yielded an estimated rental income of £20,000 – a very substantial sum at the time, whose spending he tackled with enthusiasm and considerable success. On his coming of age in 1770, he held an extravagant party for 15,000 guests; the bills record consumption of "31 bullocks, 50 hogs, 50 calves, 80 sheep, 18,000 eggs...." An embroidered suit which he may have worn on this occasion is in the possession of the National Museum of Wales. Career Williams-Wynn's family had been powerful in politics for several generations, and Sir Watkin effectively controlled several Parliamentary seats and led a Tory faction in the House of Commons, though he was less involved in politics than his father, and tended not to lead his faction decisively. The influence of the family had declined during his long minority. He served as a Member of Parliament for Shropshire from 1772 to 1774, and for Denbighshire from 1774 until his death in 1789 aged 39. He was criticised for poor attendance. He was Lord Lieutenant of Merionethshire from 1775 to 1789. Patron of the arts Sir Watkin made a Grand Tour to Europe from June 1768, returning by February the next year for his wedding in April. In Rome Pompeo Batoni painted him with some companions, and a classical subject, Bacchus and Ariadne was commissioned later, in 1774. The Rococo silver-gilt toilet service he gave to his first wife, by the London goldsmith Thomas Heming, is now in the National Museum of Wales. The Neoclassical grave monument for her is by Joseph Nollekens, in St Mary's Church, Ruabon, Clwyd. Sir Watkin played a significant role
