William Carey was the second son of Sir Thomas Carey, of Chilton Foliat in Wiltshire, and his wife, Margaret Spencer, daughter of Sir Robert Spencer and Eleanor Beaufort, and grandson of Sir William Cary of Cockington, Devon, an eminent Lancastrian. This Cary family were anciently recorded in Devon, and originally held the manors at Cockington and Clovelly in that county. Eleanor was the daughter of Edmund Beaufort, 2nd Duke of Somerset, whose brother John Beaufort, 1st Duke of Somerset, was the father of Margaret Beaufort, Countess of Richmond and Derby, grandmother of King Henry VIII; thus William and Henry VIII were third cousins. William's maternal aunt was Catherine Spencer, Countess of Northumberland, and through her, he was first cousin to Henry Percy, 6th Earl of Northumberland, the former suitor of his sister-in-law Anne Boleyn. On 4 February 1520, he was married to Mary Boleyn, the elder daughter of Thomas Boleyn, 1st Earl of Wiltshire and his wife, Lady Elizabeth Howard. They resided at Aldenham in Hertfordshire. Shortly after their marriage, Mary became the mistress of King Henry VIII. The Boleyns received grants of land, and Carey himself profited from his wife's unfaithfulness, being granted manors and estates by the King while it was in progress. Carey was also a noted art collector, and he introduced the famed Dutch artist, Lucas Horenbout, to the Kingdom of England in the mid-1520s. Perhaps one of the reasons the athletic King Henry VIII favoured Carey was the fact that Carey appears to have been fond of activities such as riding, hunting and jousting. Carey distinguished himself in jousting at the Field of the Cloth of Gold in 1520. Anne Boleyn, Mary's sister, caught Henry's eye a year after his affair with Mary ended. Henry proposed marriage to her in 1527. William Carey did not live to enjoy his sister-in-law's prosperity, since he died of the sweating sickness the following year. Brian Tuke, Henry's secretary at the time of Carey's death wrote this to Lord Legat the day after his death: "Now is word common that M. Cary, which before I came lay in the chamber where I lie, and with whom at my first coming I met here in this place, saying that he had been with his wife at Plashey, and would not be seen within, because he would ride again and hunt, is dead of the sweat. Our Lord have mercy on his soul; and hold his hand over us." He died greatly in debt, and his wife was reduced to pawning her jewellery before Queen Anne Boleyn arranged a pension for her.
Children of William Carey and Mary Boleyn
William Carey and Mary Boleyn were the parents of two children:
Henry Carey, 1st Baron Hunsdon. He was ennobled by Queen Elizabeth I just after her coronation and created Knight of the Garter in 1561. When Henry was dying, Elizabeth offered him the Boleyn family title, Earl of Ormonde, which he had long sought, but he refused the honour.
Because of Mary's affair, it has been suggested that Catherine and Henry may have been instead Henry VIII's biological children . The veracity of this claim is the subject of historical debate.
