In 1950, my great aunt Lily Murphy (Anna Goodwill in the book) left England for an adventure of a lifetime. She traveled with the Medical Missionaries of Mary to Ogoja, Nigeria to teach the leper children. The Rainwater Secret is her story.
The Medical Missionaries of Mary are still doing great medical missionary work all over the world. See www.mmmworldwide.org
The MMM constitution is below:
You are Missionaries of Mary. Work with all people of good will. Join resources with them especially in the field of health, so as to bring about a world of justice and peace, where true human development is fostered, and human dignity and rights are respected.
