Song Yu, pen name Ssangcheongdang, is said to have built the Ssangcheongdang pavilion at Songchon-dong, Daejeon. Many sources give his dates as 1389-1446, and he is described as a seventh-generation ancestor of Song Jun-gil.
Song Yu was a grandson of Song Myeong-ui, who is said to have kept his loyalty after the fall of Goryeo and settled at Hoedeok, his wife's family home, beginning the clan's long residence there. One article says Song Yu's mother, of the Ryu clan, brought her son from Songdo to Hoedeok and laid the family's foundation; details differ between sources.
The pavilion he built, Ssangcheongdang, is described as a window onto early Joseon architecture. Song Gye-sa's two sons were Song Yo-nyeon (Moksa-gong branch) and Song Sun-nyeon (Jeongnang-gong branch), and Song Gye-jung is the founder of the Sajik-gong branch, together forming the three main lines of the clan.
His sons Song Gye-sa and Song Gye-jung gave rise to the Moksa-gong, Jeongnang-gong and Sajik-gong branches.
