Lady Sukmok of the Im clan[2] (Korean: 숙목부인 임씨; Hanja: 肅穆夫人 林氏) was the daughter of Im Myeong-Pil who became the 10th wife of Taejo of Goryeo[citation needed] and the mother of Crown Prince Wonnyeong.
[3] Her clan was not clear, but it was believed that she came from the Jinju Im clan (진주 임씨; 鎭川 林氏).
[4] Although Wonnyeong's wife was unrecorded, they had 1 son, Crown Prince Hyodang (효당태자)[5] and he later died in 976 due to Wang-Seon (왕선) who murdered him as the part of a policy of revenge against the aristocratic deterrence policy.
