You might be surprised to learn that some of the most well-known royals aren't actually using their real names! Yep, we were shocked when we found out that the Duke of Sussex's actual name isn't Harry. Like many of us, the royals are often given family nicknames which stick or in the case of some monarchs, they choose to go by a regnal name.
When Princess Elizabeth was asked which name she wanted to rule under, when she ascended the throne in 1952, she is said to have responded: "My own, of course." However, some of her ancestors have opted for different monikers and similarly the Queen's heir Prince Charles could choose a different name when he ascends the throne. Find out which royals haven't been using their first names…
