I assign the variety of origins in place names to be found in my corner of Pennsylvania. There's everything from Welsh (see the Mordor assignments for a brief list) to Lenape.
A personal favorite (besides all of the Welsh places) is Wawa, which means Canada goose in Lenape. Just makes me laugh to have a place (and convenience store chain) named Wawa.
Just so everyone doesn't think everything here is interestingly named, there's a street named Street Road. And a newer cross street to Street Road quite logically named New Street Road. Not very original, but entertaining anyway.
