So, who does use the royal surname regularly? Royals who don’t have a title or another last name. Prince Harry and Meghan Markle, for example, named their son Archie Mountbatten-Windsor. Archie has no royal title, Time reports.
But using this surname isn’t a strict royal rule, and sometimes people choose to use a different one. Prince William, for example, used a different naming practice for his children, who are all princes and princesses. His children don’t have a legal surname at all, but they do need to use a last name at school. Instead of Mountbatten-Windsor, they use the name of their father’s royal title. Prince William is the Duke of Cambridge, so his kids use the last name Cambridge.
Also, if a royal woman marries a non-royal, she’ll take his last name and so will her children, as per the Queen’s decree. Lastly, members of the royal family who aren’t descendants of Queen Elizabeth still use the surname Windsor, as decreed by King George V in 1917.
