Yong An

Korean: there is only one Chinese character for the An surname; it means ‘peace’. Some sources indicate that there are 109 An clans, but only six can be documented. All had one common founding ancestor, named Yi Wǒn, who migrated from China to Shilla Korea in AD 807. Yi's three sons played a major role in resisting Japanese aggression during the reign of the Shilla King Kyǒngmun (861–875) and received the surname as a reward from the king. It is now quite a common Korean surname and can be found throughout the peninsula.
