Jennifer Teege was shocked to discover her grandfather was a Nazi concentration camp commandant. Her mother never told her, and as a child she never knew her father - a Nigerian student with whom her mother had a brief affair. This is her story.
Five years ago in northern Germany, in Hamburg, I was in the central library and I came across a book. It was wrapped in a red cover and for some reason I was immediately drawn to it.
The title, translated into English, was I Have to Love My Father, Right? and it had a small picture of a woman on the front who looked faintly familiar.
So I took the book and quickly went through it. There were a lot of photos and as I looked at the book I felt something was wrong.
At the end, the author summed up some details about the woman on the cover and her family, and I realised they were a perfect match with what I knew about my own biological family.
So at that point I understood that this was a book about my family history.
The woman in the picture was my mother, and her father was Amon Goeth, the commandant of Plaszow concentration camp near Krakow.
