Auguste Charlois who discovered 317 Roxane named for Roxana from what area
317 Roxane:  The name was chosen by F. Bidschof, an assistant at the Vienna Observatory, at Charlois's request; Bidschof chose to name it after Roxana, the wife of Alexander the Great, and at first used the spelling Roxana. Roxana: Roxana (Ancient Greek: Ῥωξάνη ; Old Iranian "Raoxshna"; sometimes Roxanne, Roxanna, Roxandra and Roxane) was a Sogdian princess of Bactria and a wife of the Greek Macedonian king, Alexander the Great.
