I have pictures of family members at the turn of the 20th century
(some end of 19th century). I know that it is possible to categorize
a tradiional Jew by his clothing: Is he a Chassid or a Mitnaged and
if a Chassid, what group he belonged to. Is there a reference book
that can help me determine where I should categorize my ancestor?
Can I deduce more facts >from just a picture?
