The Coraline Slave Theory

Are other father and other wybie created by other mother or are they originally from somewhere else? As we know the other world In Coraline is a very mysterious and scary world that has stirred up theories for a total of 13 years. While most people are focused on the cat, coraline never escaping, beldams transformation, and the bugs. I think people are overlooking something else.. the other father and other wybie.
