I have very little information. I'm 45 my mother and father divorced when I was young maybe 8 or 10. She is Korean and became a US citizen sometime in the 70's her original name was Pyon Oksun she changed it to Sonya Mitchell or Diane Mitchell. I think she remarried. My father was in the Air Force the divorce was done while stationed over seas in Japan. My brother and I are curious if she alive and well. I don't have any other information she should be between 66 to 70 years old. Any assistance would be greatly appreciated.
