There is a new public group for descendants of Meretz Jewish families.
I have a number of families that I am descended from or related to that were part of this Jewish community, although some lived in nearby Rotnitsa.
Frankel, Rushinski, Cohen, Romanov (probably), Efrati (Ephrath), Bernstein, Tsirelstein
