William Neville, 1st Earl of Kent

William Neville, 1st Earl of Kent KG (c. 1405 – 9 January 1463) and jure uxoris 6th Baron Fauconberg, was an English nobleman and soldier. He fought during the latter part of the Hundred Years War, and during the English dynastic Wars of the Roses.

Born circa 1405, he was the second son of Ralph Neville, 1st Earl of Westmorland, and his second wife, Joan Beaufort.

His mother was the legitimised daughter of John of Gaunt, 1st Duke of Lancaster and Katherine Swynford. John of Gaunt was the third surviving son of King Edward III of England and Philippa of Hainault. William was therefore a great-grandson of Edward III. However, the terms of the legitimisation of the Beaufort family specifically excluded them and their descendants from succession to the throne.

William was one of a number of the Neville sons to make a good match, marrying the Fauconberg heiress Joan Fauconberg and taking the title Lord Fauconberg — just as his nephew Richard Neville married the Warwick heiress and became Earl of Warwick. William's marriage took place at some point before 1422. His wife was four years older than he was and was described as an idiot from birth. The Fauconberg estates were in North Yorkshire, a centre of power for other members of the Neville family.

He seemingly had a conventional military career during the earlier part of Henry VI's reign. Knighted in May 1426, he was serving on the Scottish Borders in 1435. In 1436, he was serving with Richard, Duke of York, in France — his first contact with a man who was later to receive his allegiance. By 1439, he was a field commander in France, with Lords Talbot and Scales. At the siege of Harfleur in 1440, he was made a Knight of the Garter for his part in the campaigns of 1438-39, in particular the capture and garrisoning of Meaux.
