Aged 24 years when she married in 1896 so born 1871-72. Lotte Proskauer's notes (courtesy of PF) name her as Martha Hirschberg and give her date of birth as 05/02/1872. Yad Vashem records the deportation of Martha Mathilde Hirschberg born 05/02/1872 from Breslau to Theresienstadt concentration camp on 27/02/1942 and thence to Treblinka extermination camp on 23/09/1942.

Not mentioned in Sonja Delander: Nothmann Chronicle, 1974 among the children of Caecilie Freund geb. Nothmann, but her marriage record identifies her parents.
