Fans are already eagerly awaiting a royal baby from newlyweds Prince Harry and Meghan Markle. The two have now been married for less than three weeks. Markle and Prince Harry are now called the Duke and Duchess of Sussex, but according to Us Magazine, their children may not inherit royal titles. In the past, the Sussex dukedom has only been passed down to male heirs. Thus, if the newlyweds have female children, the Sussex title may die out.
