If Prince Charles has his way, Prince William and Prince Harry will have very different names.

[For example, Prince William has spent 40 years as William Wales (to honor his father's longtime title of Prince of Wales), William Cambridge (to honor his own title of Duke of Cambridge from 2011 to 2022), and now as Duke of Wales. He is again taking the name of Wales. With the addition of Mountbatten Windsor, things are very confusing in terms of surnames. [e.g., William Arthur Philip Louis and his brother Prince Henry Charles Albert David (yes, Harry is a nickname). But if the brothers' father, King Charles, had his way, the Mirror reports, they would have very different names.

When William was born in June 1982, it took Prince Charles and Princess Diana a week to announce his name. According to the paper, Prince Charles wanted to name his first son Arthur, but Princess Diana suggested William, "a more robust name" like William the Conqueror, royal historian Robert Lacey wrote in his book Battle of Brothers," he writes. Philip honors Prince Philip, and Louis honors Sir Louis Mountbatten, Prince Charles' beloved mentor who was assassinated in 1979, three years before William's birth.

Prince Charles and Princess Diana also disagreed about Harry's name, and wanted to name their second son, born in September 1984, Albert, the birth name of Prince Charles' grandfather, King George VI. Albert was chosen as a middle name, as was Charles (the obvious choice) and David, the name by which Edward VIII was called by his family. David was Charles' uncle, who abdicated the throne in 1936 to marry an American divorcee, Wallis Simpson, who eventually took the throne. (Incidentally, David has an incomprehensible number of middle names. His full name is Edward Albert Christian George Andrew Patrick David, seven names. Bring this trivia to your next royal dinner party.)

Arthur and Albert do not sound the same. Speaking of royal names, you will hear Prince Charles' full name, Charles Philip Arthur George, at least a few times during his coronation at Westminster Abbey on May 6.
