Prince Harry and Meghan, the Duke and Duchess of Sussex, have changed the names of their children. Archie and Lillibet have been given the new surname Sussex according to the new sussex.com website recently launched by Harry and Meghan.

On their birth certificates, both Archie and Lillibet were given the surnames Mountbatten-Windsor, the name decreed by the Queen as the surname of the royal family in 1960. The name is used by all male-line descendants of the Queen, except princes and princesses who are styled Royal Highness.

So William, Prince of Wales, does not technically have a surname and nor does Prince Harry - even though Harry is no longer using His Royal Highness. While at school and at work they used the surname Wales, as the sons of the then Prince of Wales.

Archie and Lillibet became a prince and princess when King Charles ascended to the throne in 2022. And now the Sussexes have given their children the surname Sussex, according to their site.

A source told The Times: “The reality behind the new site is very simple — it’s a hub for the work the Sussexes do and it reflects the fact the family have, since the King’s coronation, the same surname for the first time. That’s a big deal for any family. It represents their unification and it’s a proud moment.”
