Archie and Lilibet have new last names

Prince Archie and Princess Lilibet are undergoing a royal rebrand.

On February 13, Prince Harry and Meghan Markle relaunched their official website under the new name, where the two used their royal titles: The Duke and Duchess of Sussex. The updated website, which replaces, also displays the names of their children: Archie and Lilibet Sussex.

The children had previously adopted the surname Mountbatten-Windsor, adhering to a decades-long naming tradition which states: "Descendants of the King, other than those bearing the title of His Royal Highness and the title of Prince/Princess, or by marriage to a female descendant, It will bear the Mountbatten-Windsor name.”

Archie and Lilibet were not initially granted the title Prince, Princess or Royal Highness at birth because they were not grandsons of a reigning monarch, but they will be eligible when their grandfather King Charles ascends the throne in May 2023 title.

According to The Times , Harry and Meghan quietly adopted the Sussex surname for their children at the time.

The change is consistent with Prince William's family. When King Charles named William and Kate Middleton Prince and Princess of Wales, their children George, Charlotte and Louis adopted Welsh as their surname.

As for the Sussexes, "the reality behind the new website is very simple," a source told The Times , adding, "It's at the center of what they do and it reflects the family since the king's coronation. The fact that the work was done, the same surname was the first time . ... It's a big thing for any family. It represents their unity and it's a proud moment."
