^To keep the tree of manageable size, it omits five out of the seven known legitimate children of Kim Il Sung. Other children not shown in the tree are: Kim Man-il (1944-1947; child of Kim Jong Suk), Kim Kyong-jin (1952-; child of Kim Song-ae), Kim Yong-il (1955-2000; child of Kim Song-ae), and Kim Kyong Suk (1951-; child of Kim Song-ae). A stillborn daughter is also omitted. Kim Il Sung was reported to have had other children with women who he was not married to; they included Kim Hyŏn-nam (born 1972). Also, only some of the descendants of Kim Jong Il and Kim Jung Un (Kim Il Sung's successors) are included.
^Korean names often have a variety of transliterations into English, which can be confusing. For example, "Kim Jong-chul" may also be written "Gim Jeong-cheol" or "Kim Jŏng-ch'ŏl" among many other variations. See Korean romanization for more information.
^Official North Korean biographies of Kim Jong Il list his birth year as 1942. The Korean calendar is based upon the Chinese zodiac which is believed to characterize one's personality. The year 1942 (Year of the Horse), in addition to being 30 years since Kim Il Sung's birth may be viewed as a better year than others, thus creating a motive to lie about a birth year.
^Official North Korean biographies of Kim Jong Un list his birth year as 1982. The Korean calendar is based upon the Chinese zodiac which is believed to characterize one's personality. The year 1982 (Year of the Dog), in addition to being 70 years since Kim Il Sung's birth, may be viewed as a better year than others, thus creating a motive to lie about a birth year.
^Birth year for Kim Ju-ae is not publicly known. She may have been born in either late 2012 or early 2013.
