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.
North Korean cult of personality
In keeping with the modern mythologies that pervade North Korea's version of history, which is seen as crucial to the cult of personality and political control, it is alleged that Kim Jong-il was born on Mount Paektu at his father's secret base in 1942 (his actual birth was in 1941 in the Soviet Union) and that his birth was heralded by a swallow, caused winter to change to spring, a star to illuminate the sky, and a double rainbow spontaneously appeared.
