Emperor Kōkaku
Go-Momozono's Imperial Family lived with him in the Dairi of the Heian Palace, he never officially married and only had children with a court lady named Konoe Koreko (近衛維子). This family included at least 2 sons who died in infancy, and one 10-month-old daughter at the time of the Emperor's early death. Emperor Go-Momozono became ill in 1779, but his daughter was not eligible to become empress due to her age. When it became clear that the Emperor would not survive, his aunt former Empress Go-Sakuramachi had him adopt a son on his deathbed. The adopted son was from the Kan'in branch of the Imperial family, and would become the next Emperor. Go-Momozono died on December 16, 1779 at the age of 21 and his adopted son "Prince Morohito" became Emperor Kōkaku in the following year. Go-Momozono's only daughter Princess Yoshiko would later become Kōkaku's chief wife ("chūgū").
