@ Q: Thanks! Not much to add about La perdriole. The Lied, Art Song and Choral Text gives it as collected in Burgundy hence "eune perdriole que va, que vient, que vole" vs standard Fr. "une perdriole, qui va, qui vient, qui vole" but that doesn't mean it originated there.
Btw, partridges don't roost in trees, they do on the ground but they can fly, not high nor for long either but they do. A mother with her chicks runs, she'll even run in an opposite direction or fly a little pretending to be wounded to draw attention on her to try to save her brood.

About the Cinderella drift, Wiki page states that the oldest version is the one the Greek historian Strabo 1 century BC collected but a later Chinese version was written long before Perrault wrote his. The Catalan and Italian Wiki pages point that the girl having tiny feet made sense in Chinese culture and it was a Chinese prince's normal expectation. The Spanish article tells the Chinese story and the slippers were solid gold, not glass.
