Karl and his mother Gertrude Hirschland, from http://www.jugend1918-1945.de/
A recently posted project of life histories of German youth who grew up during National Socialism features the story of our cousin, Charles Hannam, nee Karl Hirschland. We previously told Charles’ story here and here.
The German Youth site is in German, but is roughly translated by Google through using the Chrome browser. Here is the full link to cut and paste into Chrome.
The Youth site itself is worth browsing for the heartrending stories of other young people in Germany from World War I through World War II.
Much thanks to Fabio for this link, whose contemporary photos of Essen are featured here.

Simon Hirschland wrote a letter of recommendation for my grandfather – Hugo Moses – who worked for Mr. HIrschland as a foreign exchange dealer from January 1, 1921 through March 31, 1939. It’s quite a remarkable letter. I’d be interested in learning more about the Hirschland descendants. I live in New York City with my wife and children.
