At one time my ancestor Albert Rapp tried to tell one of his daughters about his Korean wife and kids. She was upset, because it meant he had cheated on her mother, so she refused to listen. She remembers him trying to show her a picture of his wife and two or more children. I don't know if it is even possible for us to track this family down. This would have been during his enlistment with the Air Force sometime between 1940 and 1960.
