Since the Mongols at the time of the empire didn't have the Latin script in which English is written, there will likely be variations for the spellings of many names. I used spellings from a translation of The Secret History of the Mongols, which is an old text written about the Mongolian Empire and Chinggis Qahan (Genghis Khan) in particular.
