A Reverend Mother was a title held by female members of the Bene Gesserit who had completed training to an advanced level. Typically, Reverend Mothers (and Holy Sisters) had three names: The first was a Latin male name, the second an English female name, the third an Arabic or exotic name. Examples of such naming include: * Gaius Helen Mohiam * Alma Mavis Taraza * Quintinius Violet Chenoeh The leader of the Bene Gesserit, the Mother Superior, was always chosen from the Reverend Mother ranks.
