Well, someone wanted to give a male character my mother's name, once... And my father's nickname and one of my male cousin's name (here a very typical male-only name) have been assigned to females before. One of my very oldest nicknames keeps coming up as character name for the opposite sex, too. Different culture spaces are odd things.

(I still cannot picture a person named Nikita as woman, either... Note that all real-life Nikitas I have met or know of are very male and very Russian. Apparently some movie has a female titular character by that name.)
