Of course, Charles has been given some of these titles whilst Elizabeth was the Queen of the UK however, not all of them were obtained during this time. A few of his titles include; the Lord of the Isles, Duke of Rothesay, Duke of Cornwall, Earl of Chester, Earl of Carrick, Baron of Renfrew, and Great Stewart of Scotland.
