MacDuff?
Spoiler Alert
In MacBeth, the witches tell King Macbeth of Scotland (who killed Duncan to ultimately take the throne) that he could not be beaten by a man born of a woman. MacDuff, who beheads MacBeth late in the play came into the world through a Caesararean section, and hence was not “born” of a woman.
I was musing that MacDuff, not having been born, could not be a naturally born subject (in a monarchy) nor a naturally born citizen (under a democratic republic).
