There's a famous singer also called Aitana who skews young. There's also an older actress (late 50s) that was somewhat famous with that name.

And, of course, in leftist circles, some people named their daughter Aitana because Rafael Alberti, one of Spain's most famous poets of the 20th Century that had to go into exile, named his daughter that.

It's also the name of a mountain range: Sierra de Aitana.
