Trusted Across Three Reigns: Sir William Fitzwilliam’s Tudor Career

On this day in Tudor history, 3 October 1559, Sir William Fitzwilliam, gentleman of Prince Edward’s privy chamber, MP, court insider, and later deputy chancellor in Ireland under Mary I, died and was honoured with burial in St George’s Chapel, Windsor Castle. He was one of those capable, steady figures who moved quietly through the Henrician, Edwardian, and Marian courts, and kept being trusted. Who was he?

• Born to a family steeped in royal service.
• Gray’s Inn training - legal polish for a life in administration.
• Household service to Sir William Fitzwilliam, later Earl of Southampton
• MP for Guildford (1542), New Shoreham (1547), Berkshire (1553, 1559).
• At court: to Prince Edward’s privy chamber (1544), rising to chief gentleman (1545); trusted by Somerset and Northumberland.
• Knighted and made Lieutenant of Windsor Castle & Keeper of Windsor Great Park by 1552.
• Under Mary I: dispatched to Ireland, on the council; deputy chancellor (1555); exposed misconduct by Sir Anthony Leger; rewarded with a 21-year lease of Donaghmore.

Quick note: he’s not the later Elizabethan Lord Deputy with the same name. Why he matters: a Dublin-born second son who, through competence, discretion, and flexibility, became a trusted royal servant across three reigns - from household retainer to the prince’s inner circle and high Irish office.
