Rozmirovich was born in Petropavlivka in 1886, the daughter of Theodore Maish, an immigrant from Luxembourg and Mariia Krusser from Moldavia.

However, after serving the year in prison, Rozmirovich was allowed to go into exile abroad rather than being sent to Narym, leaving her daughter with Yevgenia.

In March 1917 she relocated to Petrograd, where she helped organise for the party among military units based in the city and became editor of Soldatskaya Pravda.

In 1922 she was sent to work for the Rabkrin on the direct orders of Vladimir Lenin, initially heading its legal department.

Between 1924 and 1930 Rozmirovich served as a member of the Central Control Commission of the Communist Party of the Soviet Union.
