The Duchess of Sussex is due to give birth any day now – with the million dollar question over the tot’s name unanswered.
But one thing for sure is the baby won’t be born with an HRH title, meaning it won’t be a Prince or Princess.
Instead, if the baby is a boy he will be called Earl of Dumbarton, and if a girl she will be Lady Mountbatten-Windsor.
This is because of a law made by Prince Harry’s great-great-grandfather King George V from over 100 years ago in 1917.
He ruled that only the eldest son of the Prince of Wales’ son can have a royal title, massively limiting the use of royal titles.

The rule reads: “The grandchildren of the sons of any such Sovereign in the direct male line (save the eldest living son of the eldest son of Prince of Wales) shall have and enjoy in all occasions the style and title enjoyed by the children of Dukes of these Our Realms.”
But in 2012 the Queen brought in new rules for Prince William so that all of his children would become Princes or Princesses – not just Prince George.
And according to experts, royal courtesy dictates that the eldest son of a Duke – in this case Harry – can use one of his father’s “lesser” titles.
So because Harry was awarded the title Earl of Dumbarton by the Queen on the morning of his wedding, this will likely be passed down to the royal baby if it is a boy.
Yet if it is a girl she will simply be Lady (first name) Mountbatten-Windsor, and any subsequent sons would be Lord (first name) Mounbatten-Windsor.
The Queen can step in, however, and issue a new Letters Patent that would see Harry and Meghan’s child awarded an HRH title, which she did for William’s kids.
But royal experts have told Daily Star Online they think Meghan and Harry will take the matter out of Her Maj’s hands and snub any such offer.
Joe Little, managing editor of Majesty magazine, told us: “We don’t know if Harry and Meghan want their firstborn to be a prince of princess.
“As things stand a boy will be Earl of Dumbarton and a girl Lady (Name) Mountbatten-Windsor.
“When Charles becomes king all his grandchildren automatically upgrade to HRH and Prince or Princess.
“This already applies to the children of the Earl and Countess of Wessex but they have decided not to use the royal style and titles.
“Given that Harry is now sixth in line to the throne, and will go further down, he and Meghan may well follow the Wessexes’ example.”
Charlie Proctor, editor of Royal Central, instead thinks it is unlikely the Queen will offer a title as Harry is so far down the line to the throne.
“When the Duke and Duchess of Sussex’s child arrives within the next few weeks, he or she will not be granted the title of Prince or Princess,” he told us.
“This is because in 1917 when George V issued the Letters Patent, it read that ‘the grandchildren of the sons of the Monarch in the direct male line (save only the eldest living son of the eldest son of the Prince of Wales) shall have and enjoy in all occasions the style and title enjoyed by the children of Dukes of these Our Realms.’
“This means, in theory at least, Harry & Meghan’s child will be styled as a Lord or Lady rather than Prince or Princess.
“That being said, the Letters Patent was issued more than 100 years ago – times have changed. It wouldn’t completely surprise me if The Queen breaks with tradition and affords the Sussex children royal titles.
“I think it is still very unlikely though, and if Meghan gives birth to a son he shall be the Earl of Dumbarton. If she gives birth to a daughter, she will be Lady Mountbatten-Windsor.”
