Look at the photo of the old road at Piney Grove, Maryland. A bit of nostalgia. Piney Grove MD
There are (and were) many places with that name, including Piney Grove manor in Delaware and Piney grove Landing in North Carolina, Piney Hill in Maryland, Piney Hollow in ...., etc.
Dozens of Piney grove cemeteries.

The name cannot be localized because it is everywhere.
