## Clan

In the traditional Korean clan system, which is still the basis of family registry in South Korea, each clan is distinguished by its bon-gwan, the notional ancestral seat of the clan. Typically each clan claims a different person as its founder, although there are exceptions. A total of 109 An clans are extant today. However, most of these are very small. The majority of Ans claim membership in the Sunheung Ahn clan. The Kwangju and Juksan clans are also quite large as well; in addition to these, the Tamjin, Gongsan, Chungju, Dongju, Jeuongwon, Ansan, Jecheon, Angang, and Jucheon clans are significant.
