Lady Yi gave birth to the future Queen Consort on 17 November 1851 (18 October 1851 in lunar calendar).
This led to Lady Yi and her daughter to move from Seomark-ri, Geundong-myeon, Yeoju to the House of Gamgodang (감고당; 感古堂),[a] where her husband's relatives lived.
When living with her in-laws in Gamgodang, it was decided in 1861 that Min Seung-ho would be her adoptive son as it was believed at the time that only males could continue the family line.
When Queen Min was expecting in 1871 and 1873, and as per Royal custom for childbirth, Lady Yi was brought into Gyeongbokgung's Gyotae Hall to help ease her daughter's delivery.
[9][b] Isabella Bird, a British explorer and writer, wrote about the assassination in her 1898 book Korea and Her Neighbours:[10] "She had cut many lives short, but in doing so she had not violated Korean tradition and custom, and some excuse for her lies in the fact that soon after the King's accession his father sent to the house of Her Majesty's brother an infernal machine in a shape of a beautiful box, which on being opened exploded, killing her mother, her brother, and her nephew, as well as some others.
