Edit: I was so very wrong. It seems like New England (still not a state) is more or less the most agreed upon region although Ohio and possibly New York seem on the table.
Sorry not from the states just moved here recently and I've been working at learning all the states and capitals plus the areas they fall under.
I often see a fair amount of back and forth about what is considered the "south" or "frontier" but it seems the Midwest is pretty well agreed on by everyone no?
Unrelated, I thought New England was a state.
