Robert Ogburn, 57, is a Korean-American adoptee who has returned to the country he was born in — as a diplomat. Raised an only child, Ogburn’s story includes an unexpected adoption twist and insights on how Korea and its perception about adoptees has changed over the years. And like so many other adoptees, Ogburn talks about a quest to know more about his past, and of the all-too common realities of an elusive paper trail.
