“The Comprehensive Collection of Family Lineage” is a valuable resource for Korean Genealogy. The title of this record is ManSeongDaeDongBo (만성대동보, 萬姓大同譜). Generally only prominent individuals and their lineages and clan founding ancestors were included. It covers 361 Korean lineages and 136,000 people from about 100A.D. to 1933 A.D.. The record was published during the Japanese colonial period of Korean history. It is basically a multi-family collection of family trees. Cross-referencing this record with a family JokoBo provides additional insights and validation to Korean genealogy research. The record is divided into 3 volumes.
