Hi Kay, I am searching my Korean ancestors who went to China to around 1920s and left during WW II. They had few businesses in China and Russia. My Grandmother was 11 years old when she left Seoul, Korea to Harbin China with her parents in 1920s.Her first husband was a Korean and they had one boy. Her second husband was my grandfather who was a Russian Jew named Robert Kovtun in Harbin, China. In 1936, she left Harbin to Moscow with her husband and her 3 children. Her husband was captured by Stalin at September 1937 and disappeared. She returned to China to look for her parents in 1938 but the WWII disabled the railroad to Harbin. It took her 8 Years to reach to her parents' place, they were gone. Shenever seen them and her 3 brother , one sister again. I know all their names beside her mother's first name. I am looking for them or any information about them. Any record of business, marriage certificate in Harbin or ship list?
