Who is Canon of Ingleheim from Pope Joan and what is their importance?

The Canon of Ingleheim is a cruel and depraved man who is mentally and physically abusive to his wife and his children. He lives a life of cold, sparse poverty in service to his village as their religious leader. As a young missionary, the Canon rescues his wife, Gudrun, from the Saxon area of Germany where the devastation and destruction from the Vikings forced her into starvation. Her only payment in exchange is to listen to him preach.
