Suffolk, Charles Brandon, Duke of Suffolk (c. 1484–1545)

English nobleman and soldier. He distinguished himself in the French campaign in 1513. In 1515 he secretly married Mary Tudor, sister of Henry VIII and widow of Louis XII of France. This at first made Henry extremely angry, but Suffolk soon regained his favoured position and later acted for Henry on a number of occasions.

He was created viscount Lisle in 1513, and duke of Suffolk a year later. He was the grandfather of Lady Jane Grey.
