Geographic dispersal

Franziska's 5 children spread across Prague, Sobau (Soběslav), New York, and Karlsbad via brother Daniel. The Bertha Schwartz / New York connection documents an 1880s-1890s Bohemian-Jewish emigration to the United States, whose descendants would have been safe through the Holocaust era.

Holocaust trajectory

• Rosa, Henriette, Hugo Mohr / Ekstein families, Prague — high Protectorate-era risk
• Leo Mohr family, Sobau — Czech rural transport risk 1942-1944
• Bertha Schwartz family, New York — safe through the Holocaust era
• Daniel Porges, Karlsbad — extreme Sudeten-area risk after September 1938; Karlsbad fell to the Nazis after the Munich Agreement
