Prince William and Duchess Kate’s third child, who was born on Monday, already boasts a very long, fancy title: His Royal Highness Prince Louis Arthur Charles of Cambridge.
Prince Louis won’t have is a last name, at least not officially. When the children of the Queen and Prince Philip need to use a surname, they use Mountbatten-Windsor. That last name first appeared on an official document in 1973, when Princess Anne got married. And that will be the case unless Prince Charles decides differently when he becomes king. Prince William and Duchess Kate often use the surname Cambridge for their family, and Prince Harry has often used Wales as his surname.
Here are the full names and full titles of key members of the royal family, though those titles can change depending on where they are in the world at the time.
