This is so interesting. I was familiar with most, but not all. For instance, I think I knew Wisconsinite, but I've not heard Wyomingite or New Hampshirite. And I've DEFINITELY never heard Massachusettsan, which sounds patently ridiculous. Not that I have a better suggestion for a person who lives in Massachusetts. That's a tough one. And do we really not say someone is Indianan? It's just Hoosier?? That seems strange.
