William Parr, Marquess of Northampton, Earl of Essex, 1st Baron Parr, 1st Baron Hart KG (14 August 1513  28 October 1571), was the only brother of Queen Katherine Parr, the sixth and final wife of King Henry VIII. He was a "sincere, plain, direct man, not crafty nor involved", whose "delight was music and poetry and his exercise war" who co-authored a treatise on hare coursing. He was in favour with Henry VIII and his son Edward VI, under whom he was the leader of the Protestant party, but having supported the desire of the latter to be succeeded by the Protestant Lady Jane Grey, was attainted by Edward's Catholic half-sister, Queen Mary I. He was restored by her Protestant half-sister, Queen Elizabeth I.
