After her mother died, she went to live with a bachelor uncle, Baron Anton von Handel-Mazzetti, in Steyr in 1901.

This was in the middle of her most productive period when her books were being serialised in magazines as well as being published and enthusiastically received.

[2] When 25 members of the PEN Club passed a resolution to protest the Nazi book burnings in 1933, von Handel-Mazzetti and other nationalist and Catholic authors did not agree and quit the Club.

[4] During World War II, she stayed in Linz, apart from when the bombing was severe and she briefly moved to Elisabethinen in 1944.

Having lived in Linz for the rest of her life, von Handel-Mazzetti died there in 1955.
