Basically a romp through the Irish Folklore Commission's binders of oral histories done in the 1930's and 1940's - if it dealt with a banshee, it's in here.
A stray reference in the notes made me realize banshee stories migrated into the coal valleys of Pennsylvania, and survived into the mid-20th century.
In our house growing up in the 1960s, my mother would still refer to anyone towelling off wet hair as "looking like a banshee."
We are civilized about one inch deep.
