>>[his mother] the former Rosa Salvatha, of Sephardi-Jewish heritage<< https://www.haaretz.com/jewish/this-day-in-jewish-history/1.680188I wonder if she was in fact from a Sephardi family that settled in Lithuania (although I have researched the topic of Sephardim in Eastern Europe for many years now, I am constantly faced with incredulity by scholars and laymen alike who believe the phenomenon was negligible at best). Is anyone familiar with this family?
