京 （きょう/kyou・きょ/kyo） - males and females?

Yes, this is just a result of romanizing Japnese. The name is always きょう in hiragana. The romaji spelling for きょう can be kyou or kyoo or kyo or whatever (romaji is not japanese so it doesn't matter so much), but the pronunciation for きょう is kyou/kyō with prolonged o as in 京都. 京都 is sometimes spelt kyoto as well but it's never きょと but きょうと.
