I'd much rather see
Aaron, in honour of the wonderful man who wrote "Appalachian
Spring", rather than Appalachia itself. Or
Apollonia, if we're going for soundalikes, as it seems a better namesake.
Nice a place as the Appalachian Mountains are (very beautiful), they're also associated with some rather extreme poverty in my mind--one might as well name a child Philippines or Laos or Somalia.
