The roads are signed and in the county GIS as "Nvno" so the current tagging is correct. It doesn't seem the first part of the name is ever meant to be a translation from Cherokee, so translating it back doesn't make sense (Old Indian Nvno: https://www.hcpress.com/front-page/nov-15-public-hearing-set-nearly-50-new-road-names-watauga-county.html )
