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.
On 14 December 1490, at about sixteen years of age, Eleanor married Edward Stafford, 3rd Duke of Buckingham, who was five years old when his father, the rebellious 2nd Duke of Buckingham, was attainted and executed for high treason.
Edward Stafford's mother, Catherine Woodville, went on to marry Jasper Tudor, the first Duke of Bedford and thirdly, Richard Wingfield.
At seven, Edward became the third Duke of Buckingham and also the ward of King Henry VII's mother, Lady Margaret Beaufort.
