Researching a dayan in Ciechanow #rabbinic
I am interested in researching a rabbi who was a dayan in Ciechanow. I am
interested in knowing whether there are any special resources available for
this type of research. I am also wondering whether the documents associated
with the work of the Beit Din in Ciechanow might have survived.
Researching: PERLEMUTER, KALFUS, GUZIK(ER), KAC, FILUT, Ciechanow
