hello leodegar, my name is peter clausen. by chance i have red your postings about arpad and mathilde pindter in ancestry. i am located in vienna/austria. from some of your post i assume that you are located in innsbruck. to make sure that everyone can read this text i still write in english and not in german.
my grandparents and my parents have been close friends to arpad and mathilde (tante thilde). the friendship was so close that after the deaths of my grandparents mathilde moved into their flat here in vienna, at "gumpendorferstrasse". i have a few more information about thilde and would be pleased to pass over everything i know to you or who ever is interested in these stories.
by the way: wasn´t their daughters name "viola"??
