In the British Royal Family, only the sons of the monarch are entitled for royal titles to be bestowed upon their children.
This is why Prince Charles’ sons William and Harry are princes, and Prince Andrew’s daughters Beatrice and Eugenie are princesses.
But it is believed the Queen made an exception for Princess Anne, offering her the option of a title for her firstborn.
However, when the couple welcomed their first child in 1977, both Anne and Mark decided to decline the offer.
