John Comyn IV of Badenoch

John Comyn IV (c. 1294–1314) was the only son of the Red Comyn, who was killed at Dumfries in 1306. Sent to England by his mother, he saw his Badenoch lordship forfeited, probably at Robert Bruce's St Andrews parliament of 1309. He married Margaret Wake, by whom he had a son Aymer, who died in infancy in 1316.

Comyn returned to Scotland in the English army and was killed leading a cavalry charge against the Scottish schiltrons on the main day of the Battle of Bannockburn, 24 June 1314.
