My point was that if your ancestor in Europe was ethnically German or
Austrian, the probability that a patrilineal descendant survives in Europe
is pretty good, because Germany and Austria were prosperous and 'expanding'
into the 20th century. If your European ancestor was ethnically Czech or
Slovak (and simply called himself German or Austrian because that was his
legal citizenship), the probability of your patrilineal line dying or
daughtering out in Europe would be much higher.
