Sir William Norreys (c. 1441 – before 10 January 1507)[1] was a famous Lancastrian soldier, and later an Esquire of the Body to King Edward IV.
Though he survived the battle, when so few Lancastrians did, he was forced to make peace with the recently proclaimed King Edward IV.
By August 1461, he was appointed Steward of both the Royal manors of Cookham and Bray, adjoining his family estate of Ockwells.
In 1483, shortly after the July crowning of King Richard III, William reverted to his anti-Yorkist sympathies.
On 16 June 1487, he commanded the Royal Forces, including his son, Sir Edward Norreys, at the Battle of Stoke Field against Lambert Simnel.
In 1461 Norreys married Jane de Vere (d. before 1471), sister of 13th Earl of Oxford, by whom he had four sons and two daughters: On 25 April 1472, Norreys married Isabel Ingoldesthorpe, Marchioness of Montagu (1441 Cambridgeshire – 25 May 1476 buried: Bisham), daughter and co-heiress of Sir Edmund Ingoldesthorpe (1421–1456) and Joanna Tiptopf (1425–1494), and the widow of the 1st Marquess of Montagu, by whom she had two sons and five daughters.
[3] Norreys married thirdly, about 1478, Anne Horne, widow of Sir William Harcourt and Sir John Stanley (d. 29 June 1476), and daughter of Robert Horne, Alderman of London, by Joan, daughter of Edward Fabian.
