"The Queen's middle name is Alexandra," explains Arbiter. "Alexander would be the male form of that and, in a way, pay tribute to the Queen."

Additionally, His Royal Highness the Prince of Cambridge's first name, George, is a nod to Elizabeth's father, King George VI.

As for the prince's middle name, it's been speculated Louis is a tribute of sorts to Prince Phillip's (the Queen's husband) grandfather Prince Louis Alexander. The name also figures into the newborn father's given name, William Arthur Philip Louis.
