New Prince of Cambridge follows a long line of famous faces called Louis
Prince Louis shares his name with a host of famous faces including jazz musicians, an Oscar-winning actor, a heart-throb pop star and of course a long line of French kings.
Perhaps the best-known Louis is trumpeter and singer Louis Armstrong, who blazed a musical trail for much of the 20th century and helped turn the jazz music pioneered in his home city of New Orleans into a global artform.
The moniker is popular in the jazz world as there is also Louis Jordan - the pioneering musician and bandleader whose songs are celebrated in the hit musical Five Guys Named Moe - and Louis Prima, who sang I Wanna Be Like You in the 1967 Disney film The Jungle Book.
Modern-day music fans may be more familiar with singer Louis Tomlinson who, with his fellow One Direction band-mates, set female hearts a-flutter when they burst on to the pop scene, following their appearances on The X Factor.
Irish entertainment manager Louis Walsh was a judge on that season of the TV talent show when One Direction were created by Simon Cowell.
On the big screen, actor Louis Gossett Jr played the no-nonsense, straight-talking Marine Corps Gunnery Sergeant Emil Foley in the 1982 film An Officer And A Gentleman.
He had a number of memorable scenes opposite the film's lead, Richard Gere, and won a Best Supporting Actor Oscar for his performance as the drill instructor.
Body builder Louis "Lou" Ferrigno used his physique to good effect playing the Marvel comic book character The Incredible Hulk in the hit TV show.
And France had a succession of monarchs named Louis, including Louis 16th, who was executed in 1793 during the French Revolution.
