Korean clans of foreign origin

Korean clans of foreign origin (Korean: 한국의 외래 귀화 성씨) refers to Korean clans (also "bon-gwan") that claim descent from a progenitor of foreign origin, based on genealogical records. == Authenticity == The ancestral origins of many Korean clans of foreign origin cannot be historically verified outside of a clan's own genealogical records: the ones from the Joseon period, as well as several from the Goryeo period, can be considered historical and factual, but the ones dating before the Goryeo period are impossible to confirm.
