Rina/Renya Niskier was born in 1920 in  Ostrowiec, daughter of Dov and Rivka Niskier. As she got older, she became involved in Zionist activity and left to Lodz in 1938 to a Hachshara for agricultural training as part of the Noar Hazioni. She returned to Ostrowiec and helped in the education and care at a childrens home. Later she ran away to Warsaw, where she met Janina Grundgand Kulwieć  through Edzia Fefer, who helped Rina by making Aarian documents and place her to work with Mrs. Wojciechowska doing household help until liberation.

She then moved to Lublin and then to Italy, to make Aliya to Palestine in August 1945 and married Feivel Sheves.
