Shin Seong-yong (申成用) is the founder of the Goryeong Shin clan. Under Gojong, the 23rd king of Goryeo, he passed the civil service examination and received the honorary post of Geomgyo Gungigam (檢校軍器監). Because he arose from the local gentry of Goryeong, once the seat of the flourishing kingdom of Daegaya, some hold that his line descends from Daegaya royalty or nobility, though no records confirm this. The Goryeong Shin are regarded as a lineage distinct from the Pyeongsan Shin, despite sharing the surname Shin (申).
