One of my closest friend is a gender sociologist (and I'm talking with them _now_)... And don't consider Sand as trans. They cite other names as historically trans (Violette Morris, and for fun Jeanne D'Arc). Sand was definitely on the queer spectrum but I (and my friend) don't think she was trans. She had relationship with both women and men, dressed as often in men and women clothes.

According to the best (or worst) authorities, George Sand slept around with quite a few men.
