[Opinions] Re: American Names
Perhaps other Americans will disagree with me, but I don't think that there are names typical of the areas you mention. Other than the South being fond of double-barreled girls names, and some names sounding "country" so seeming Southern, the only "area-typical" names I can think of is Spanish names being more common in areas with a lot of Latinos.
The South is unique. The fact that some names sound Southern doesn't mean that every area has its typical names.
