As "user unknown" stated in the comments of another question, there should exist German dialects, where "es" is a common pronoun (instead or beneath "sie") for a woman. ("es" as pronoun is translated to "it", "sie" as pronoun is translated to "her".)
Richtig ist, dass "es" sehr abwertend klingt. In manchen Dialekten ist Es aber für Frauen in Gebrauch (Es Gerda hat Kopfweh).
[My free translation: "It is right, that "it" sounds disrespectful. But in some dialects is "it" used for women (It Gerda has headache).]
To be honest, I can not believe this, and so I want to ask:
In which dialect is "es" a common pronoun for a woman?
