In her recent interview with PEOPLE, Meghan, 43, explained that her children do not use the titles ‘His/Her Royal Highness’ at all.

Instead, she revealed that Archie and Lilibet’s official surname incorporates her and Harry’s titles as the Duke and Duchess of Sussex.

She disclosed that they have been using ‘Sussex’ as their family surname for quite some time, explaining that the title was originally granted to her and Harry by Queen Elizabeth II on their wedding day in 2018.

Meghan spoke about the significance of this surname, saying:

“It’s our shared name as a family. And I guess I hadn’t recognised how meaningful that would be to me until we had children. I love that that is something that Archie, Lili, H and I all have together.”

She also expressed how the name is deeply tied to their relationship, adding:

“It means a lot to me. It’s part of our love story.”

However, Meghan’s comments have sparked debate among royal watchers, with some questioning the validity of using ‘Sussex’ as a surname rather than Harry’s legal last name.

One royal fan, as quoted by the Daily Mail, remarked:

“Her name is NOT Meghan Sussex. Her name is technically Rachel Mountbatten-Windsor. Sussex is a county in England & part of a courtesy title—NOT her last name.”

Another critic noted:

“Meghan Markle married Henry Mountbatten-Windsor, not Harry Sussex!”

Before King Charles’ ascension to the throne, Archie and Lilibet originally carried the surname Mountbatten-Windsor. However, following their grandfather’s rise to the monarchy, they became known as Prince Archie of Sussex and Princess Lilibet of Sussex.

Now, they are informally referred to as Archie Sussex and Lili Sussex.
