Prince William and Kate Middleton’s royal title was nearly given to senior royals, but was blocked by a senior member of the royal family.
They were given the title Duke and Duchess of Cambridge, originally intended for Prince Edward and Dutchess Sophie.
Edward and Sophie were given the title of Earl and Countess of Wessex, a title traditionally bestowed upon the monarch’s younger sons upon their marriage.
In 2010, Edward and Sophie changed their titles again, becoming the Duke and Duchess of Edinburgh. They chose not to use the titles of prince and princess for their children, Lewis and James.
