The young royal, who celebrated his fourth birthday last week, will have to choose his own surname before joining other preschoolers in the new school year in September. For some young children it's not all about picking the perfect pencil case from Woolworths, after all.
As Hello reports, before 1917 the Royal Family had no surname and instead were known by the name of the house they belonged to. Due to the pan-european nature of royal marriages, the houses often had distinctly German sounding names.
During the First World War, when Britain was at war with Germany, the family changed their house name from "Saxe-Coburg-Gotha" to "Windsor." Many of Queen Elizabeth's descendants then adopted the official surname "Windsor," before adopting "Mountbatten-Windsor" to incorporate Prince Phillip's original surname, too.
But when Prince William and Prince Harry attended school, they paid tribute to their father by using his royal title "Wales" as their surname. Young George could choose to carry on from his grandfather's legacy and be known as George Alexander Louis Wales, or he could pay tribute to his own dad's formal title, and be known as George Alexander Louis Cambridge.
Though if we had the opportunity to choose our very own surname at such an age, we have to assume we’d opt for something a little more daring than Windsor or Wales. George Targaryen or George Potter have a certain ring to them, after all.
