If the child is a boy, he could instead become Earl of Dumbarton – one of the side titles the prince received from the queen in the morning of his wedding. The eldest son and heir of the apparent duke can use one of his father's minor stamp titles, according to Debrett's. The daughter could be Lady (first name) Mountbatten-Windsor and other sons Lord (first name) Mountbatten-Windsor.
The Earl of Dumbarton, George Douglas, was a Scottish nobleman and soldier. He was badly wounded in a duel with the duc de Normandy in 1669 and the papers reported him dead due to the severity of his injuries.
History behind popular baby names
The nation gave its money to a child named Diana (probably after Prince Harry and William's mother). While Diana Spencer was the only member of the royal family with this name, the moniker has regal connotations. In Roman mythology, Diana was the goddess of hunting and chastity, and the daughter of Jupiter, king of the gods.
Victoria, the second favorite name, has a clearer royal history. Of course, Queen Victoria is the best known royal one, though – although (as the fans of the ITV show know), this was not her real name. Alexandrina Victoria was born, but changed her name when she became queen.
