In Disney's Tangled, what is the birth name of the thief known as Flynn Rider?

In Disney's Tangled, the thief known as Flynn Rider was born Eugene Fitzherbert.

Eugene introduces himself as Flynn Rider, a confident fictional persona he created after growing up poor and reading adventure stories about a charming rogue. His real identity becomes important as his relationship with Rapunzel develops and he becomes more honest about his past.

The character is voiced in English by Zachary Levi, who also performs several songs in the film. Rapunzel initially knows him only as the wanted thief who enters her tower while fleeing royal guards.

Flynn Rider is often confused with Maximus, the palace horse who pursues him, or the Stabbington brothers, former partners who betray him. Eugene's surname is Fitzherbert, not Rider.
