I have noted in replies to Suzanne's original request for information on the name STREUSLER a couple of alternate spellings, one of which was STREISSLER.
In the publication "Totenbuch Theresienstadt - Deportierte aus O(umlaut)sterreich" there is mention of a Rosalie STREISSLER, born on17.10.1879 transported >from Vienna to Theresienstadt on 10.10.1942; and further transported >from there to Auschwitz on 23.10.1944.
