NEW THUMBELINA! WOOOO!
I finally finally FINALLY found another female variant! Here, right here! Google Translate, thank you!
Yes, it's in French.
But the story's Spanish and it's a variant of the generic Thumbling tale with a female protagonist called Maria comme l'ail, or Maria like Garlic. Still have to find out what that means in Spanish, but still, it's another girl.
Researching folktales and fairies, with a focus on common tale types.
