Rabbi Elchanan UNGER of Piatek and Warsaw (1824-1927) seems to have
connections to the Dabrowa Unger Dynasty, though I can't quite place
him on public trees.
from a Geni tree (which may or may not be correct) the Dabrowa familystarts with Tzi Hirsch Unger, who had a son, Mordecai David b. about
1770. Mordecai David then had 5 sons, Avraham Elchanan, Moshe, Menachem
Mendel, Jehiel Tzi and Yosef. I believe these are the ancestors of the
current Babover Rebbe, Mordecai David Unger.
A number of these names are similar to the family of the first Elchanan
Unger I mentioned above. This Elchanan was son of Mordecai Motl Mendel,
son of Natan. Elchanan's brothers were Natan, Naftali and Joel Tzvi.
Some of them were said to have been >from Dabrowa.
I am a relative of Elchanan's first wife, Shifra Halpern.
I'd appreciate any insight into the connection, if there is one. Thank
