Edmund of Woodstock, 1st Earl of Kent Edmund of Woodstock, 1st Earl of Kent (5 August 1301 – 19 March 1330) was the sixth son of Edward I of England, and a younger half-brother of Edward II. Edward I had intended to make substantial grants of land to Edmund, but when the king died in 1307, Edward II failed to follow through on his father's intentions, much due to his favouritism towards Piers Gaveston. Edmund still remained loyal to his brother, and in 1321 he was created Earl of Kent. He played an important part in Edward's administration, acting both as diplomat and military commander, and in 1321–22 helped suppress a rebellion against the king.
