Found an interview with her speaking about the deportations to the Riga ghetto in Latvia in 1942.
Her birth date, as she states it, does match up. Her mothers in a footnote at the bottom of the first page however doesn't. (Note: it's pretty likeable Pauline Katscher became Pavla Katscheróva as Czechoslovakia became independent of Austria in 1918)
She also mentions her father's death in 1937 (on page 153) like here on Geni . Not quite sure yet, if this is the same person - she seems to have changed her name from Gerta to Gertruda.
The information is taken from this book, only in German though (starting at p. 151):
