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.
This website is based on my research into folklore. Currently, the focus is on my project surrounding thumblings, i.e. other versions of Thumbelina and Tom Thumb from different cultures. Other things may occasionally pop up.
