Hi David- I enjoyed reading your article on Henryka Cohn. She was a first cousin of my grandfather’s mother. My grandfather was acquainted with Egon Schiele in Vienna. I have a small sketch he drew of my Opa in 1917. His mum Elise Moll lived with her uncle Hugo Cohn and Regine briefly before she married Jacques Rose after she lost her parents in the Ringtheaterfire of 1881. Elise’s mother was born Henriette Cohn, the sister of Hugo. My family came to the UK in 1939. I was trying to do Henriette’s family tree online when I came across your lovely article, so toda raba and shalom!
