Kyŏn Ae-bok, often referred as Lady Kyŏn in some historical sources, was the daughter of Kyŏn Hwŏn[4] and wife of Pak Yŏng-gyu.
[5] The couple had a good-relationship with Wang Kŏn since Wang regarded Pak as his older brother.
[6] Due to this, their eldest daughter became one of Wang's wives and their other daughters became Wang's third son's wives.
These daughters were later known posthumously as Lady Dongsanwon, Queen Mungong, and Queen Munseong.
