Kim Jong-suk
Kim Jong-suk married Kim Il Sung in the Soviet Union, most likely in 1941. On February 16, 1941 (or 1942, sources vary), in the Soviet village of Vyatskoye, Kim Jong-suk gave birth to Kim Jong-il, who was given the Russian name "Yuri Irsenovich Kim," and the nickname "Yura." In 1944, Kim Jong-suk gave birth to a second son, Kim Man-il in Korean and "Alexander" or "Shura" in Russian. In 1946, she gave birth to daughter, Kim Kyŏng-hŭi. Augustina Vardugina, a woman from Vyatskoye, was in her teens when Kim Il-sung’s guerrilla group camped there. She remembers Kim Jong-suk, and how she would come to the village to barter military rations for chicken and eggs. Her son, Kim Jong-il, would be holding her hand.
