Daughter of Leizer Oshrin (born 1862, Lithuania – killed in 1941, Riga) and Zelda Oshrin (born 1862, Lithuania – died 1925, Riga).

She completed two classes of elementary school in Riga in 1892. In 1924, she moved to Liepāja. In 1941, she was evacuated to the village of Sosnovka in the Kirov Region, and in 1945 she returned to Riga.
