In Hungary, "Aranyhaj" ("Golden-Hair") can refer to Rapunzel, Goldilocks, and various Hungarian fairy tale heroines. The Russian equivalent "Zlatokosa" is a rather similar case.
There is more than one Goldilocks. It can refer to either the Goldilocks in "Goldilocks and the Three Bears" or the heroine of Madame d'Aulnoy's "The Story of Pretty Goldilocks," a princess who holds Engagement Challenges. Their French names are different, though, with "Goldilocks and the Three Bears" starring "Boucles d'Or", while d'Aulnoy's Goldilocks is called "La Belle aux cheveux d'or".
Among French fairy tales, many names are reoccurring. Aimée can be either the heroic princess of Madame d'Aulnoy's "The Bee and the Orange Tree" or the villainous princess of Madame Leprince Le Beaumont's "Aurore and Aimée."
Madame d'Aulnoy has two princes by the name of Chéri. One appears in "Finette Cendron" and the other appears in "Princess Belle-Etoile." There is also a Madame Leprince Le Beaumont story called "Prince Chéri."
In Russian fairy tales, more often than not, the titular character is called either Ivan the Fool or Ivan-Tsarevich. The female leads are usually named Maria or Vasilissa.
