>I would have also guessed "Berenstein", but to be fair, I barely knew how to spell when I read through those books. I didn't know about the Berenstain alternate universe until long after it was a thing, and I this was my first reaction as well. I never really knew how to spell it, and I hadn't see one of those for many years since. I also think it's one of those easily confused suffices: -ein, -ine, -ien, -een, -urg, -erg, etc.
