How strange. I've located a phone book for 1947 which includes Co. Durham, Newcastle and Northumberland and, although other Station Hotels are listed, there's no entry for the one in Ebchester. Although it wouldn't list his name, it might have given some clues.

Just before you put up your first request for Margaret Bell the other week, we'd driven though Ebchester on our way to Derwentwater - only go that way a few times a year!
