Why Prince William and Prince Harry’s children have different surnames

Prince William and Prince Harry’s children, unlike most male siblings in the UK, do not have the same surname, which may surprise royal fans.
Unlike the Cambridge kids, Archie and Lili have a different last name.

The Duke and Duchess of Cambridge’s children, Prince George, eight, Princess Charlotte, seven, and Prince Louis, four, all have the surname ‘Cambridge,’ after their father’s title.

At his school, Thomas’s Battersea, Prince George is known as George Cambridge. Similarly, Princess Charlotte is known as Charlotte Cambridge, and Louis is known as Louis Cambridge at nursery.

A declaration made by the Queen in Privy Council in 1960 stated that male-line descendants of the monarch, without royal styles or titles, shall bear the name Mountbatten-Windsor, according to the royal family’s official website.

When Harry and Meghan’s son Archie was born in May 2019, Buckingham Palace announced that the royal baby would be known as Master Archie Harrison Mountbatten-Windsor, a nod to the Queen and the late Duke of Edinburgh, who were his great-grandparents.

As a result, Archie Mountbatten-Windsor, Harry’s son, bears the surname Mountbatten-Windsor. Lilibet Diana, his younger sister, also has the same surname.

William and Harry grew up with the surname ‘Wales,’ which they used at school, university, and in the army. Lieutenant Wales was William’s title, while Captain Wales was Harry’s.

Because they do not have royal titles or styles, Archie and Lili take the surname Mountbatten-Windsor.




This is because their father, Prince Charles, holds the title of Prince of Wales, but after their marriages, William and Harry received new titles from their grandmother, the Queen, which they are expected to pass down to their children.
