When they got married on April 29, 2011, Prince William and Kate Middleton each received three titles from Queen Elizabeth. While they are best known as the Duke and Duchess of Cambridge, Her Majesty also bestowed the newlyweds with the titles Earl and Countess of Strathearn, as well as Baron and Lady Carrickfergus, per My London. These titles are location specific: when William is visiting Scotland, he uses his title Earl of Strathearn. When Kate is in Northern Ireland, she is referred to as Lady Carrickfergus.
William and Kate aren’t the only royals with location-based titles. According to British Heritage, Prince Charles has three Scottish titles: Duke of Rothesay, Earl of Carrick, and Barron of Renfrew. However, he typically is referred to as Duke of Rothesay, and Camilla Parker Bowles uses the title Duchess of Rothesay. Prior to stepping down as working royals, Prince Harry and Meghan Markle were known as Earl and Countess of Dumbarton in Scotland. In Northern Ireland, their titles were Baron and Baroness Kilkeel, per Tatler.
When it comes to the royal titles, William and Kate have signaled they may change protocol and modernize the monarchy. When they visited Wales in March, William and Kate impressed a royal fan with their relaxed demeanor. Furthermore, after the controversial Caribbean tour, a royal source told the Mirror, “They want to be more approachable, less formal, less stuffy and break away with a lot of the tradition.”
