How do I research the name Rosenzweig? in that town.?

MODERATOR'S NOTE: Go to the Jewish Records Indexing-Poland database
at www.jri-poland.org (and click on "Search Database"). Enter the
surname you seek and enter Czestochowa in the town field. You can
also search by broader geographical designations to find family who
may have lived nearby. Also, all messages should be signed with the
full name of the writer.
