William Fitzwilliam (died 1534)

Sir William Fitzwilliam (c.1460 – 9 August 1534) was a Merchant Taylor, Sheriff of London, servant of Cardinal Wolsey, and a member of the council of Henry VII.

William Fitzwilliam was the second son of John Fitzwilliam, esquire, of Greens Norton, Northamptonshire, and Helen Villiers, the daughter of William Villiers, esquire, of Brooksby, Leicestershire, by Joan Bellers, the daughter of John Bellers of Eye Kettleby in Melton Mowbray, Leicestershire.

Fitzwilliam began his career as a London merchant in the service of Sir John Percyvale. He was admitted to the livery of the Worshipful Company of Merchant Taylors in May 1490. He served as Warden in 1494 and 1498, and was elected Master in 1499. He resided in Bread Street ward, and later in St Thomas the Apostle. In addition to his activities as a London merchant, he became a Merchant of the Staple at Calais. In 1503 he was elected alderman for Broad Street ward. In January of that year he was influential in obtaining a new charter for his Company which allowed the Merchant Taylors to encroach on the interests of the other London companies. In 1505 he was a candidate for Sheriff of London, but was not elected; in 1506 Henry VII intervened to secure the office for him.

In 1510 the Mayor and Aldermen elected him as Sheriff a second time. He refused to serve, and in consequence was fined 1000 marks and disenfranchised. His franchise was restored and the 1000 mark fine was remitted by the Court of Star Chamber on 10 July 1511; nonetheless, he left his career as a London merchant and entered the service of Cardinal Thomas Wolsey, who had aided him during his quarrel with the City authorities. He became Wolsey's treasurer and high chamberlain, and was appointed to Henry VII's council.
