Margaret, Countess of Salisbury (1473-1541) was the daughter of George, Duke of Clarence and Isabel Neville. Her uncles were King Edward IV and King Richard III. She was one of very few women in 15th-century England to be a peeress in her own right, as the heiress of her parents; and one of the few survivors of the royal York dynasty by the end of the Wars of the Roses. In 1487, the victorious Lancastrian King Henry VII gave Margaret in marriage to his cousin, Sir Richard Pole. Margaret later was executed on a trumped-up charge by King Henry VIII.
