Though the Frozen franchise has failed to provide a definitive answer, there's finally some solid speculation about what Anna and Elsa's last name is.. Ooh, interesting, thank you! Titles of Elsa and Anna are horrendously difficult to use, especially when we discuss the non-existent nobility (and where the hell were they anyway? there was just one FOREIGN duke, all the ones in Arendelle died?) Honestly, though, using "Arendelle" as a last name is a bit difficult in a way that using, e.g., "Windsor" wouldn't be. Arendelle is also the place.
