The Duke and Duchess of Cambridge have announced their new son's name: George Alexander Louis, or HRH Prince George of Cambridge.

This toes the line with tradition but we can't help noticing that they ignored a few more adventurous options. A quick look back at William's family tree reveals these zany names from royal history:

Augustus

It's a radical option, but the name Augustus comes from impressive royal lineage. Augustus was the title given to Octavian, the first Roman emperor, and also Augustus II the Strong, King of Poland in the 1600s. Prince Augustus Frederick, Duke of Sussex, was also the sixth son of "Mad King" George III. It's derived from Latin, meaning "to increase," "great" or "venerable".

Ernest

Ernest is a Germanic name, literally meaning Earnest or serious. Ernest I, Duke of Saxe-Coburg and Gotha was a Prussian general and participated in military actions against Napoleon. He was also the great-great-great-grandfather of Queen Elizabeth II and named one of his illegitimate children Ernst.
