My half sister Myeongsugi was born in South Korea around 1960-61 and was raised by my grandmother Ssi Kim until 1970 when my grandmother passed away. My mom left for the United States with an Army soldier. She took one daughter and was hoping to go back for the other. I believe Myeongsugi was then in the care of my aunt Chong Cha, born 4/7/1943 in Seoul. My mother, Kyong Cha Chon, had an uncle on her fathers side so I assume his last name was also Chon. He had children; cousins to my mom and aunt. Any information as to their whereabout would be greatly appreciated.
