I'm trying to research my family tree & know that my father's oldest brother was in the Marines (MP) stationed in China around 1928 or possibly earlier. He married a woman there (not Chinese) & brought her back to Pa. They eventually split up & she returned to China with their daughter. I recently FOUND the daughter. He was stationed near Shanghai (or so we think). How can I find out more information on his service in the Marines? He changed his last name from the one he was born with. His name was STEPHEN W JANDROKOVIC. He changed it to STEPHEN W JACKSON. When he returned home he lived in San Francisco & had remarried OLIVE RUSLER. They had 2 childrenMARILYN LEE JACKSON ISOLA HILL and STEPHEN WILLIAM JACKSON. I know Marilyn had a daugther LAUREL LEE ISOLA & STEPHEN had a son TODD JACKSON. Trying to locate any or all of these family members.
