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.
Kim Jong-il
Kim's first mistress, Song Hye-rim, was a star of North Korean films. She was already married to another man and with a child when they met. Kim is reported to have forced her husband to divorce her. This relationship, started in 1970, was not officially recognized. They had one son, Kim Jong-nam (1971–2017), who was Kim Jong-il's eldest son. Kim kept both the relationship and the child a secret (even from his father) until he ascended to power in 1994. However, after years of estrangement, Song is believed to have died in Moscow in the Central Clinical Hospital in 2002.
