He was committed to the Fleet Prison by the Privy Council, and afterwards was tried in the Star Chamber on 15 February 1581 along with his brother-in-law Sir Thomas Tresham for harbouring the Jesuit Edmund Campion and contempt of court.

[1][2][3] William Vaux married firstly Elizabeth, daughter of John Beaumont of Grace Dieu, Leicester.

Their children were: In 1557 Vaux conveyed the manors and advowsons of the family estates at Great and Little Harrowden to his second wife's grandfather, Sir Thomas Tresham I, who died in 1559 and was succeeded by his grandson, another Sir Thomas.

The Tresham Papers contain an account of the family disputes which resulted from a 1571 settlement of the properties, under which the younger Sir Thomas stood security for the payment of £500 (£226,000 as of 2025[1]) to each of Vaux's daughters by his first wife.

On Vaux's death in 1595, he was succeeded by his grandson, George's son Edward, who inherited the titles shortly before his seventh birthday.
