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-chang
Kim was born on 13 October 1948 in Yecheon, Gyeongsangbuk-do near the Sobaek Mountains. He was raised by his mother and paternal grandfather after losing his father to the Korean War at the age of two. He studied primary, middle, and high school in his hometown; he states that his home room teacher at Daechang High School left an indelible mark on him during his formative years. He matriculated at Seoul National University as an undergraduate in 1967, graduating in 1971 with a degree in commerce. He passed the State Administration Examination for Civil Servants in 1970 while in his senior year.
