A common debate

What is Beatrice II's real last name? Some portray her as being a Snicket because she was Kit Snicket 's daughter, but it would make more sense for her to be a Denouement seeing as Dewey Denouement was her father and most families take the name from the fathers side. Some other people, on the other hand, debate she is a Baudelaire because the Baudelaire siblings adopted her after Dewey and Kit had both passed away. What do you think Beatrice's real last name is?
