Courtenay was Henry VIII's uncle, having married Katherine of York, daughter of Edward IV and Elizabeth Woodville, and sister of Henry's mother, Elizabeth of York.
Courtenay had been made a Knight of the Bath at the coronation of Elizabeth of York in 1487, due to his support of Henry VII, but was attainted and imprisoned in the Tower of London in 1504 for treason due to his involvement in Edmund de la Pole, Earl of Suffolk’s plotting. He was released and pardoned after Henry VIII’s accession. He acted as sword bearer at the new king’s coronation.
