Why the new royal baby won’t have a surname
We don’t know if the Duke and Duchess of Cambridge’s third baby will be a boy or girl yet – nor do we know what name he or she will be christened – but what we do know is that the new royal baby won’t have a surname.
As royal historian Marlene Eilers told Town and Country magazine: "The royal baby will not have a last name. The name on the birth certificate will say HRH Prince or Princess, and all three names of Cambridge."
The new baby will have three names, just like siblings Prince George Alexander Louis and sister Princess Charlotte Elizabeth Diana.
Most royals don’t actually have surnames, instead they adopt the names of their titles.
For example, Prince William and Prince Harry were known as William Wales and Henry Wales throughout their school days, after their father the Prince of Wales, while Prince George's name is listed as George Cambridge.
