In the summer of 1942, parents across Nazi-occupied Yugoslavia were required to submit their children to medical checks to assess their racial purity, and nine-month-old Erika Matko was declared fit to be a "Child of Hitler." Taken to Germany as part of the Lebensborn program and placed with politically vetted foster parents, Erika was renamed Ingrid von Oelhafen. Though the Nazis often destroyed their records, Ingrid recounts here how she later discovered her origins by unearthing rare documents, including Nuremberg trial testimony about her own abduction. Following the evidence back to her place of birth, Ingrid chanced upon an even more shocking secret: a woman who, as an infant, had been given to Ingrid's biological mother as a replacement child.
