Although William was en-adapt at handling his financial matters, he was ironically appointed the office of Chamberlain in the separate household of the Duke of Richmond, the acknowledged illegitimate son of King Henry VIII and Elizabeth Blount, based at Sheriff Hutton Castle in Yorkshire. It was William who found a spot for his nephew, William Parr, later Earl of Essex, in the Duke's household where he would be educated by the very best tutors and mixed with the sons of other prominent families. Though thought to be a wonderful environment for Parr and his nephew to flourish in, the household was not a great passport to success as Parr hoped for. Henry VIII was very fond of his illegitimate son, but had no intention of naming him his heir. It has been claimed that Parr and his sister-in-law, Maud Parr, coached William to make sure that he ingratiated himself with the Duke, in case the Duke became heir to the throne but there is no factual evidence to support this claim.
