Nicholas Vaux, 1st Baron Vaux of Harrowden

Katherine's husband, Sir William Vaux, whom she had married not long before she obtained her letters of denization, was attainted in 1461[5] and later slain at the Battle of Tewkesbury in May of 1471.

[6] Despite her husband's misfortune, Katherine Vaux remained loyal to her mistress: she stayed by the Queen during her imprisonment in the Tower of London, and on Margaret's release in 1476 went with her into exile (as she had done earlier in the 1460s), living with her until her death six years later.

Not only was he active and diligent in local government but he was also frequently at court attending all the great state occasions at home and abroad until his death; in 1511 he entertained Henry VIII at Harrowden.

Given the important command at Guisnes, he distinguished himself during the Tournai campaign in 1513 and then in the missions (he had had some earlier experiences in negotiating, chiefly with Burgundy) to the French King about the English withdrawal and the several royal marriage treaties.

Vaux was a natural candidate for election to Parliament, although in the absence of so many returns for the early Tudor period he is known to have been a Member only in 1515 when he and Sir John Hussey took a memorandum on certain Acts from the Commons up to the Lords.
