Bill,

You may also want to consult with Sarah W. Vodrey, Historic Site 
Manager, at The Museum of Ceramics in East Liverpool, Ohio. While the 
Museum specializes in ceramics manufactured in East Liverpool, they 
also have collections and documentation for regional ceramics produced 
in West Virginia and Pennsylvannia, including some from Beaver and 
Beaver Falls, PA.

Best of luck,
Hank Lutton
