Why Prince William and Prince Harry's children will have different surnames

Prince George, Princess Charlotte and Prince Louis all take the surname 'Cambridge'

Unlike most male siblings in the UK, Prince William and Prince Harry's children will not share the same surname. William and Kate's little ones – Prince George, Princess Charlotte and Prince Louis – all have the last name 'Cambridge', taking after their dad's title, the Duke of Cambridge. By the same model, it can be assumed that any children Prince Harry and Meghan Markle have will use the surname 'Sussex', after their father's official title, the Duke of Sussex.

William and Harry grew up with the surname 'Wales', using it at school, at university and during their time in the army. William was known as Lieutenant Wales while Harry had the rank of Captain Wales. This is because their father Prince Charles' title is the Prince of Wales. But following their marriages, William and Harry were granted new titles from their grandmother the Queen, and their children are expected to take these on.

Prince George, five, started junior school last year, enrolled as George Cambridge. His sister Princess Charlotte, three, is also known at her nursery as Charlotte Cambridge. In a similar vein, Princess Eugenie and Princess Beatrice also use the surname 'York' after their father Prince Andrew, the Duke of York. 

Members of the royal family traditionally don't use a surname; they are simply known by their first name or title in the public eye, and His or Her Royal Highness. But as descendants of the Queen, they can also take the surname 'Mountbatten-Windsor'. According to the royal family's official website, in 1960 the Queen and her husband Prince Philip decided that their descendants would take the surname 'Mountbatten-Windsor', to reflect both of their last names and differentiate them from the rest of the royal family.

William and Kate are the proud parents to George, Charlotte and newborn baby Prince Louis. The Duke and Duchess of Cambridge welcomed their third child in April, just three weeks before attending Prince Harry and Meghan's wedding. Royal watchers are hoping that the Duke and Duchess of Sussex, who tied the knot in mid-May, will soon hear the pitter-patter of tiny feet in their own home.
