Family tree, i.e. charts used in genealogy, is a record of the totality of one's ancestors from its originator to recent times by connecting diverse family units applying certain principles. Moreover, it is a family history where blood relations and other related factors are depicted in a systematic way including the personal details of the family members.
The purpose of producing genealogical records in Korea can be summarised into three: pay respect to one's ancestor; express deference to the wider family; and to unite blood relations. In other words, one can trace their family customs and cherish virtues of their ancestors; mantain harmony by understanding the family relationship; and reinforce unity by establishing the hierarchical order within the wider family.
