Unfortunately, I never found one; not even in Turkish, yet alone in English. There are books by Suraiya Faroqhi written in German, but also translated into English. However, I have no idea how good and reliable her books are. By the way, Since the Turks became Muslims and up until 1940th Ottoman Muslim women used to wear Niqab along with Hijab. Non-Muslim women back then wore only Hijab without Niqab. That's how they were distinguished. After the fall of Ottoman many things have been destroyed and stolen from the people. Here is one piece of a history: http://img88.imageshack.us/img88/3411/19151917.jpg
