Who is Sean Michael? An Adoption Mystery: Part 2, The Baby Book


Sean’s adoptive mother, Martha Ann, kept a “baby book”: a binder stuffed with newspaper clippings, greeting cards, baby photos. Sean can’t explain why some of the documents and articles are there, but their presence has offered some tantalizing clues – including the possibility that Sean is an infant survivor of one of South America’s bloodiest purges. Sean had his DNA tested to see if the results lent credence to any of these theories – and we introduced him to a professional genetic genealogist who might make sense of the scientific data. Stay tuned for Part 3: Sealed Records.
