When he or she is born next month, Prince Harry and Meghan Markle‘s royal baby is expected to make history in more ways than one. And because the world is obsessed with all-things baby Sussex right now, many people have been wondering what the little one’s last name will be. Or, frankly, if Harry and Meghan’s child will even need a surname as a member of the British royal family.

Well, according to the royal family’s official website, Harry, 34, and his 37-year-old wife’s baby will most likely need a last name because the child’s title won’t be “His/Her Royal Highness.”

“Members of the royal family can be known both by the name of the royal house and by a surname, which are not always the same. And often they do not use a surname at all,” the site explained. Like Harry, you can expect his baby to follow in his footsteps and use a surname once he starts attending school. But what exactly will that last name be?

When the Duke of Sussex was still a kid, his parents, Prince Charles and the late Princess Diana, enrolled him and his older brother, Prince William, in school as Harry Wales and William Wales, respectively, because of their father’s royal title. Since Prince Charles, 70, is the Prince of Wales, it only seemed right that they use “Wales” as their surnames in school — and we can expect little baby Sussex to do the same!

Prince William, 36, also followed his dad’s lead and enrolled his eldest son, Prince George, and daughter, Princess Charlotte, in school as George Cambridge and Charlotte Cambridge, respectively, because he and his wife, Kate Middleton, are known as the Duke and Duchess of Cambridge. And when Prince Louis starts school too, he will most likely be called Louis Cambridge by his teachers and schoolmates.

Although King George V officially gave the royal family the surname “Windsor” in 1917, Queen Elizabeth later changed this to “Mountbatten-Windsor” when she began her reign in 1952 because she also wanted to honor her husband Prince Philip‘s surname. The more you know, right?!
