Cinderella's real name was unknown.
Didn't her step sisters call her Cinder-Ella because she fell asleep and woke up covered in ash and cinders?
The story was written in French.I don't know what her name was in the original French, but I know that in modern-day French the word for "Cinderella" is Cendrillon.She used to sit in the cinders and ashes when she was done with her work, but she doesn't specify her real name on the site.The older sister was rude and uncivil, but the younger sister called her Cinderella.The word for squirrel fur back then was "vair", not to be confused with the words "glass" and "verre".
Since she was a servant, they called her Cinderella.
She didn't have a first name in the Brother's Grimm version.The step- mother and step sisters called her Cinderella because of the mess she had to clean.
She has a real name.Her step- sisters call her Cinderella because she gets cinders in her dress and hair while sitting by the fire.
