Things You Didn't Know About Kate And William's Marriage

We all know them as Prince William and Kate Middleton. And of course we're also familiar with their official titles, the Duke and Duchess of Cambridge, which Queen Elizabeth II gave them on the day of their wedding. But did you know they have two other titles as well? Since the Queen can also bestow regional titles, Prince William is known as the Earl of Strathearn in Scotland and Baron Carrickfergus in Northern Ireland, while Kate is Countess of Strathearn and Lady Carrickfergus.
