According to Hello! Magazine, on the morning of his wedding to Meghan in May 2018, Queen Elizabeth granted Harry the title Duke of Sussex.

With this new title, Harry no longer used the surname Wales and instead adopted Sussex as his designation. Likewise, when Meghan married him, she became the Duchess of Sussex and effectively dropped Markle, becoming Meghan Sussex.

However, when their son Prince Archie was born in May 2019, his birth certificate listed his full name as Master Archie Harrison Mountbatten-Windsor. The same applied to their daughter Lilibet, who was officially recorded as Miss Lilibet Diana Mountbatten-Windsor at birth.

Interestingly, their surnames changed following the passing of their great-grandmother, Queen Elizabeth, in September 2022. With her death, Prince Charles immediately ascended the throne as King Charles III, which automatically shifted Archie and Lilibet’s positions in the line of succession.

Thanks to legislation introduced by King George V in 1917, Archie and Lilibet were finally granted the titles of Prince and Princess—just like their cousins, Prince George, Princess Charlotte, and Prince Louis.

After Lilibet’s christening in March 2023, the royal family’s official website was updated to reflect the revised line of succession.

It was also confirmed that the children would now be referred to as Prince Archie Sussex and Princess Lilibet Sussex.

Despite Harry and Meghan stepping down as senior royals in 2020, their Duke and Duchess of Sussex titles remain intact—these can only be revoked through legislative action.

So, unless an official decision changes things, the family continues to be known as The Sussexes.
