Arthur Plantagenet, 1st Viscount Lisle, KG (died 3 March 1542) was an illegitimate son of the English king Edward IV, half-brother-in-law of Henry VII, and an uncle of Henry VIII, at whose court he was a prominent figure and by whom he was appointed Lord Deputy of Calais (1533–40). The survival of a large collection of his correspondence in the Lisle Letters makes his life one of the best documented of his era. Biography Arthur Plantagenet was born between 1461 and 1475 in Calais, which was then an English possession in France. He died at the Tower of London, where he is buried. The identity of his mother is uncertain; the most likely candidate appears to be the "wanton wench" Elizabeth Wayte, although the historical record is spotty on this issue, and it is not entirely clear that Wayte is distinct from another of Edward's mistresses, Elizabeth Lucy. Another possible candidate is Elizabeth Shore. His godfather was William FitzAlan, 16th Earl of Arundel. He spent his childhood at the court of his father Edward IV. How he passed his youth after his father's death in 1483 is not known. In 1501 he joined the household of his half-sister, the queen consort Elizabeth of York, and moved to the household of Henry VII after her death in 1503. After the accession of his nephew Henry VIII in 1509, he was formally designated an Esquire of the King's Bodyguard and was a close companion of Henry's (despite the age difference). In 1514 he was appointed High Sheriff of Hampshire and made captain of the Vice-Admiral's ship Trinity Sovereign, rising to become Vice-Admiral of England. In 1519 he and his wife, Elizabeth Grey Baroness Lisle, took possession of the lands that had belonged to her father (her brother and niece having both died). In 1520, he attended his nephew, King Henry VIII, at the Field of Cloth of Gold. On 25 April 1523, Arthur Plantagenet was created Viscount Lisle. In 1524, he was invested as Knight of the Garter. He was also selected Privy Councilor, Governor of Calais, and Lord Warden of the Cinque Ports and named as Constable of Calais after the death of John Bourchier, 2nd Baron Berners on 16 March 1533. Constable of Calais The Lisle Letters suggest that as Constable of Calais he was honest and conscientious but not especially competent. Among the letters is one from Thomas Cromwell
