Mariella Mehr
Mariella Mehr was born a member of the nomadic Yeniche people. She was a victim of the "Hilfswerk für die Kinder der Landstrasse" (loosely translated, "Relief Organisation for Rural Street Children"), which separated Yeniche children from their parents. Mehr was moved between 16 orphanages and three reformatories as a child. She was committed to a mental institution four times and spent nineteen months in a women's prison.
