In 1970 I married Dwight Brown from Columbus Ohio. 1973 he died of Non Hodgkins Lymphoma. Just 3 years after serving in South Korea. I want to know if he was exposed to Agent Orange. I want to know if he was ever at the DMZ. He worked as a postal clerk. John Leary and Arlyn Baat might have known Dwight and worked with him in 1968 - 1969.
