Kristina Rzewuska was born in Vilnius. She started primary school in Vilnius in 1936 and finished it in 1939. Then a tragedy befell the family: her father, an official before the war, was imprisoned by the Soviets and finally died as a soldier of the Polish army in Western Europe at the very beginning of the Second World War. The girl and her mother moved to the periphery, Mickūnai rural district. After the war, Kristina went to a girls’ gymnasium in Vilnius and attended a state music school. Upon finishing the gymnasium in 1948, she became a student at the faculty of History and Philology of Vilnius University. On 25 March 1949, she was deported to Irkutsk region. While in exile, she wrote to Vilnius University asking for her school-leaving certificate as she wanted to continue studies at another institution of higher learning. She was released from exile in 1956. Upon return, she took advantage of the repatriation of the Polish nationals from the USSR to Poland and left Lithuania.
