Much has been said this week about Royals and their seemingly confusing titles, after Meghan Markle revealed in a shocking new interview that she, Prince Harry, and their two children share a surname.

The surprising news has prompted some followers of the family to do some digging into the other monikers of the monarchy, even finding young Prince Louis’ birth certificate.

The youngest of the Wales’ children was born on 23 April 2018 to mother Kate Middleton (or ‘Catherine, the Princess of Wales’, as some know her), and father Prince William (known formally as ‘His Royal Highness Prince William Arthur Philip Louis Duke of Cambridge’).

The latter section of 42-year-old William’s name could also be switched out to ‘Prince of Wales’, following his ascension to the position after his grandmother The Queen’s death in 2022.

We know – it’s a bit of a mouthful.

It turns out, however, that Louis followed in his father’s footsteps when it came to his full title – as his birth certificate reveals.

Obtained by CBS at the time, the official document lists now-six-year-old Prince Louis’ ‘Name and surname’ as ‘His Royal Highness Prince Louis Arthur Charles of Cambridge’. Again, the latter section could be switched to ‘of Wales’, following Queen Elizabeth II’s passing.
