Although the first four clans — Pyongsan, Goryeong, Aju, and Saknyeong — share the same Chinese character (申), they are unrelated in heritage.The Pyongsan Shin clan lineage makes up about 70% of all those with the surname Shin using the Chinese character 申.
Sin Sung-gyŏm also saved the life of King Taejo of Goryeo during a disastrous battle with Later Baekje near present-day Daegu in the early 10th century.
Another well-known family line that also uses the Hanja character 申 is the Goryeong Shin clan, descended from Shin Suk-ju, the lead scholar working with King Sejong the Great in the development of Hangul, the Korean written language.
Shin Suk-ju was also a high ranking government minister and belonged to the Hall of Worthies.
Three of five members of Shin Suk-ju's 16th generation are known to have immigrated to the United States in the 1970s, such as the physician David Sheen.
