[1] Born on 30 November 1897 in Sillian-Ahrnbach, Tyrol, Austria as Rosa Hoffman, she was the wife of fellow Austrian Resistance member Anton Stallbaumer (1888–1962), who had made a living prior to the war in the truck transport of various goods.

[5] According to Dachau records, Anton Stallbaumer arrived at the concentration camp on 10 October 1942, was designated as a "Schutzhäftling [de]," and was assigned inmate number "289406."

[7] Nazi officials then sent Rosa Stallbaumer to the Third Reich's concentration camp at Auschwitz, ensuring that she and her husband would remain separated for the duration of their imprisonment.

[10] The daughters of Rosa and Anton Stallbaumer were ultimately released from separate re-education camps with the youngest placed into the care of a Slovenian farmer (according to statements later made by her older sister, Anna-Luise).

[14] According to author Gisela Hormayr, author of the 2017 book, Wenn ich wenigstens von euch Abschied nehmen könnte ("If at least I could say goodbye to you"), as Luise (Stallbaumer) Reider reflected on her life, she noted that the last memories she had of her parents were of her father's arrest by the Gestapo in May 1942, and spending time with her mother two days later at a Mother's Day celebration.
