Royals Lord of the Isles? Find Out Which Royal Holds That Title Which royal is using the unusual title today during a trip to Scotland? By Simon Perry Published on October 18, 2016 10:16 AM Share Tweet Pin Email Photo: Chris Jackson/Getty When Prince Charles heads to the outer reaches of Britain off the coast of Scotland today, he will do so under a particular title – Lord of the Isles. The “Lord” is visiting the Isle of Lewis to attend the most important cultural festival of the Gaelic language in Scotland, the Royal National Mòd in Stornoway. He is also opening a whiskey distillery on the Isle of Harris. Lord of the Isles is one of several titles the future king carries. There’s the best-known, Prince of Wales (which by way of his first marriage brought us the Diana, Princess of Wales). And then there is the Duke of Cornwall, signifying he is head of the Duchy of Cornwall that provides his income (and, of course, provides a title for his second wife Camilla, who is the Duchess of Cornwall). And in Scotland, he and Camilla are known as the Duke and Duchess of Rothesay. Want to keep up with the latest royals coverage? Click here to subscribe to the Royals Newsletter. Charles is also Earl of Chester, Earl of Carrick, Baron of Renfrew and Prince and Great Steward of Scotland. But Charles is not alone in piling up the titles. Prince William is the Duke of Cambridge, the Earl of Strathearn in Scotland and, when in Northern Ireland, is known as Baron Carrickfergus. For his wife, that means she is the Duchess of Cambridge, the Countess Strathearn and Baroness Carrickfergus. Or simply Princess Kate. (We know, we know.)
