William Nevill, 16th Baron Bergavenny

William Nevill, 16th Baron Bergavenny (also Abergavenny; – 21 September 1744), was an English peer and courtier who held positions in the Royal Household and built a country mansion in Sussex.

Origins Born about 1698, he was the only son of Edward Nevill (1664–1701), a Captain in the Royal Navy, who died aboard HMS Lincoln off the coast of Virginia, and his wife Hannah Thorpe (1668–1764), daughter of Gervase Thorpe (died 1716), near East Grinstead.

Life On the death without children of his first cousin Edward Nevill, 15th Baron Bergavenny, he succeeded to the barony, taking his seat in the House of Lords on 12 November 1724. Deciding to leave the ancient family house at Birling in Kent, he sold inherited lands and applied the proceeds to buy a block of farmland in Forest Row, where he created a park and built in it the mansion of Kidbrooke Park, since altered into Michael Hall School. In 1737 he obtained the post of Captain of the Yeomen of the Guard and in 1739 was appointed Master of the Jewel Office. He died in Bath on 21 September 1744 and was buried at East Grinstead, being succeeded in the barony by his eldest son. An obituary poem called her: "Young, thoughtless, gay, unfortunately fair."

On 20 May 1732 he married Lady Rebecca Herbert (died 20 October 1758), daughter of Thomas Herbert, 8th Earl of Pembroke and his wife Margaret Sawyer, with whom he had four children: William Nevill, Harriet Nevill, Mary Nevill, and Sophia Nevill.
