Yolanda of Vianden

Mother Yolanda (or Yolande, Iolanda) of Vianden, O.P., (1231–1283) was the youngest daughter of Count Henry I of Vianden and Margaret, Marchioness of Namur. She joined the Dominican monastery in Marienthal, Luxembourg, against the wishes of her parents when she was very young. She later became its devout prioress and is now a historical legend.
