There is one point that I am not sure was dicussed before.
The clerks incl. the ones who wrote Policejni prihlasky in Prague sometimes mixed up the domicile (zustaendig) and the actual birth town. The same mistake happened sometimes in marriage records (esp. in Vienna) and ship manifests to US to name few exapmples. That mistake can make life of family historian quite difficult lately. The good news however is that it can direct the historian to the birth town of the father of particular person.
