Thank you so much for all this information! I vaguely remember my Uncle Frank (Fadenberger) mentioning a sister named "Rosa". That was probably his mother's name, too, as they are buried along with Franz (his father) and Gisela (his sister) in the same plot. Thanks also for the referral address to Vienna's Archive Registry! Perhaps they can give me additional identifying information on the other Fadenbergers you located (2 Marias, Josef and Josefa). My uncle returned to Vienna periodically over the years, to check on his family. They were in the Russian Occupation Zone after World War II and he provided for their support. If I remember correctly, Gisela was the last living member of his immediate family. God bless you for providing this information to our family - the lost found again, after so many years! Sincerely, R.Remer
