In Imperial Russia there was a concept called "registration." At some time,
your ancestors were registered in Voronkow. Changing one's registration was
a complicated and difficult process. Many Jews lived far >from where they
were registered. They were supposed to register births and deaths in the
town of their registration, and get their internal passports at that
location. Sometimes they didn't bother to register since it was so
difficult -- but that was a crime. Many Jews weren't registered at all,
since registrations were used for tax and conscription purposes.
