The best match I found for S. Wyrobnik was Szymon Wyrobnik born 15 March 1924 and he lived at Muhl 104 flat 1 and Hohens 43. He has a note 20.11.42. He also appears as Szymon Wrobnik.
I only found one other person at Muhl 104 flat 1 and that was Gedalje/Gedalja Wyrobnik/Wrobnik born 11 Sep 1921. He also is living at Franz 30 flat 43 and moved to Hohens 43. I also found Icchok born 26/06/1920 living at the same address as Gedalje. I'm assuming perhaps he's a cousin or maybe another brother.
I found Szymon on Yad Vashem under the "Lists of Jewish forced laborers in Schillstrasse camp" and it states he was born in Lodz, Poland, He was at Auschwitz Camp Poland, Neuengamme Camp Germany, and Ravensbrueck Camp, and Braunschweig's Schillstrasse Camp Germany where he was murdered
