Baby Name Popularity: How local is it?

We look at the national name statistics and somehow start to  assume that Isabella and Jacob are the top names all across the country.  But then we look at the state stats and see that there very much still are local preferences. 

For example, Carter, which is Number 50 nationally, is in second place in Nebraska and third in Iowa; Wyatt (60) is Number One in Wyoming (Wyoming/Wyatt?), Owen (50) is third in Vermont and fourth in Maine, and for girls, Brooklyn (37) has relocated to Utah, where she’s Number Three.

So our Question of the Week is a two-parter:

Are there any names near the top of the Social Security list that you never hear in your neighborhood/city/state/country? (Please identify where that might be.)

Are there names that seem absolutely epidemic where you live, but are not as popular elsewhere?

Any explanations?
