Eleanor Percy, Duchess of Buckingham (c. 1474[citation needed] – 13 February 1530), was the eldest daughter of Henry Percy, 4th Earl of Northumberland, by his wife, Lady Maud Herbert, daughter of William Herbert, 1st Earl of Pembroke. Eleanor Percy married Edward Stafford, 3rd Duke of Buckingham, who was beheaded in 1521 on charges of plotting to overthrow the king, Henry VIII. As a result, the Dukedom of Buckingham and estates were forfeited, and her children lost their inheritance.
