Hi all -- this is a long shot. I'm trying to find someone and all I know is their name and address (in Germany). 40+ years ago she married my father but he died shortly after and I never had any contact with her. Posting the name and address here. Not even sure if she is still alive. Any thoughts/suggestions of how I could contact her short of mailing a letter? Or if that address is still current or if she's alive? Thank you!
