Odd state

In North Carolina many counties and county seats share a name. Gastonia in Gaston County, Lincolnton in Lincoln County, Durham in Durham County. Sometimes a county has no city with a similar name. But the oddity is when a city isn't in the county with a shared name. 

For example, the city of Davidson is a couple of counties over from Davidson County. The same is true of Cherokee and Cherokee County. 

Asheville and Ashe County are five counties apart. Rockingham city is almost in South Carolina while Rockingham County is on the border with Virginia. 

Henderson is the seat of Vance county in the northeast, not Henderson County in the southwest, where Hendersonville is the seat.
