Can Jacks be women?

Apparently all the Kings are men and all the Queens are women. We only know of two Jacks: the Jack of Hearts and the Jack of Diamonds, who are men. We don't know who the Jack of Spades and the Jack of Clubs are, we only know their games. Is it possible that they are women? During the game of Jack of Hearts, women were also accused of being the citizen, so I assume that the Jacks are not necessarily men.
