Is the name Elsa copyrighted?

Could you clarify whether the name "Elsa" is subject to copyright protection? Is it a unique creative work, such as a character from a movie or book, that might be protected by copyright laws? Or is it a more generic name that wouldn't fall under copyright protection? It would be helpful to know the specific context in which "Elsa" is being used, as that could affect whether or not it's copyrighted.
