Answer:
Twain gave these two the same name on purpose. He wanted to show the reader how hypocritical Hank is. He claims that le Fay is evil and devilish. However Hank is guilty of the same things that she is. He condemns her for killing the servant and then a few hours later has her hang the entire band because he did not like the songs they were playing. He also dislikes le Fay because she claims to be some sort of sorceress. Once again, hank is guilty of the same thing. From the beginning of the novel he pretends to be a magician.
