I agree that I "really need a placename" but that is the problem. I don't have one. I only just learnt that he had a brother and sister in Germany in 1914. I wish the newspaper article had mention their names.
There are no living relatives that I am aware of who might have known or who have any papers around that timeframe saved from the family. A letter from his sibling with a return address would be very nice!
Thanks for the information.
