Thanks a lot. I have fixed 17015 Carlisle, PA to Cumberland.
19087 Wayne I have the impression that Delaware is more appropriate.
When you look at the county boundaries:
http://www.geonames.org/5186677/delaware-county.html you see the label 'Wayne' within the boundaries.
This is confirmed by wikipedia: 'Wayne is an unincorporated community centered in Delaware County, Pennsylvania, ...'.
