In page Margaret Pole, Countess of Salisbury:

"

Her second son, Arthur Pole, had a successful career as a courtier, becoming one of the six Gentlemen of the Privy Chamber and one of the noblemen who accompanied the king's sister Mary Tudor to France for her marriage to King Louis XII in 1514.[8] Arthur suffered a setback when his patron Edward Stafford, 3rd Duke of Buckingham, was convicted of treason in 1521 but was soon restored to favour. He died young (about 1526),[citation needed] having married Jane Pickering, the heiress of Roger Lewknor.[8] Margaret and her son Henry pressed Arthur's widow to take a vow of perpetual chastity to preserve her inheritance for the Pole children.[citation needed]
