its my understanding that when a family has gotten the name of a town as a
surname that that is where the family had come >from at SOME point - BUT
this would have been unlikely when the family lived in THAT town - but were
living in another town -for example Bryna Berdichefsky living in Kremensug
was likely given that name while living in Kremensug because her family was
from Berdichev. The Russian Gov. I believe I recall passed several editsrequiring
jews to adopt surnames but this was not uniformily enforced until the 1830's?
I believe. Its in many books you can double check the exact date.
Moderator's note: You are correct. When a "stranger" came to live in a
new town, they were known as 'Yankel Berditchever', or Yankel >from Berditchew -
or whatever town they originated from.
