Queen Elizabeth II is rumored to give Meghan Markle and Prince Harry’s firstborn a royal title.

Latifa Yedroudj, a journalist for Express, it is unlikely for the Duke and Duchess of Sussex’s child to be called a prince or a princess. But the baby will most definitely be given a peerage title.

According to etiquette institute Debrett, the couple’s eldest son will be called the Earl of Dumbarton, one of the titles that the Queen bestowed on his grandson after his May 19 wedding.

If Prince Harry and Markle’s eldest child will be a girl, she will be called Lady Mountbatten-Windsor. Their second child, if it will be a boy, will be referred to as Lord Mountbatten-Windsor.

The children’s future titles come in accordance to the royal succession rules, which was set by Prince Harry’s great-grandfather, King George V. In 1917, the King limited the royal family titles for future generations. However, the monarch decided to bend this rule for Prince William’s children.

As of late, Prince Harry and Markle have not yet revealed what they will name their unborn child. It has been a practice among royals to make the announcement after the baby is born.

Jessica Bridge, a spokeswoman for Ladbrokes, told Express, “Given this child will be in line to the throne, it’s probably a safe assumption that the couple will opt for a regal name that has been used in the royal family over the generations.”

In related news, Markle made her first appearance since the royal baby announcement in Australia on Monday. The Duchess of Sussex showed a hint of her baby bump in her white sleeveless dress. She and Prince Harry are currently on a 16-day tour of Australia, Fiji, New Zealand, and the Kingdom of Tonga.

The couple will also be attending the Invictus Games in Australia next week. Their overseas tour will wrap up on Oct. 31.
