She married commercial employee Josef Pollak with whom she had two daughters, Marianne (1913–2000) and Lotte (1914–1931).
Valerie Pollak was probably murdered in the fall of 1942 in the Chełmno extermination camp.
At the family grave in the New Jewish Cemetery in Prague, a plaque commemorates the three sisters.
Her first daughter Marianne emigrated to England along with her husband Georg Steiner in 1939.
She looked after the inheritance of her uncle Franz Kafka lodged in the Bodleian Library in the University of Oxford.
