Hermann is listed in the Breslau synagogue community address list (ca 1930) at the same address as Alfred: Breslau Platz der Republik 9. In 1931 he sailed to the USA, identifying Alfred at the same address as his father. It is not clear which of Alfred's wives is his mother, however it appears from the endowments Siegfried established in their wives names that they died in the 1910s, so Selma is the more likely candidate to be Hermann's mother.
