Gosh you guys are so rude..
Hi rachmaninoff_forever,
George Sand was actually the pen name of the French author Amantine-Lucile-Aurore Dupin. Back then, Female writers often used male pen names because they would make more money from publishers, who paid men more than women. Chopin and Sand never actually married, but they did live together for quite an extended period of time. Around ten years I believe.
