None of them are Danish. Elsa/Anna are as close as it gets. Just because HCA was Danish doesn't mean Ariel is!

acording to me
Belle-France
Tiana and Poca- USA
Mulan: China
Merida: Scotland
Elsa and Anna: Norway
Jasmine: Arabian Peninsula

Not sure:
Cinderella:
Snow white and Rapunzel : Germany
Aurora: England

And i don't know where is Ariel supossed to be from

France,i skipped Cinderella in france

^And Ariel's hat while she's holding the baguettes! Great argument! Thanks for all of that insightful information! I learned so much! :D I think Ariel's red hair mislead me more towards Denmark in addition to other things you debunked (Eric & Original Tale).

i learned on a video on youtube, that ariel lived in denmark. (the coast of denmark so that counts as ariel living in denmark)

@jeangreyforever: that's an incredibly detailed analysis, and wonderful observation skills!!
