Although the three daughters of Malchen Rothschild and Daniel Rosenblatt were all murdered in the Holocaust, their two surviving sons Felix and Siegmund were able to escape Nazi Germany as was their daughter-in-law Julchen Rosenblatt Rosenblatt, the widow of their son Juda/Julius. I did not have a great deal of information about Felix or Siegmund because they escaped to Argentina, and I have limited resources for research there.
