=== Regarding the title === 
  you didn't suggest what you thought would be the appropriate disambiguation for the title. The sources support either (healer) or (medium). The Daily Telegraph obituary says "healer". I suppose that was likely written by his family, but how can you avoid POV? "Alleged healer" or "charlatan" would just represent another POV. Editors are free to balance the title with counter-POVs in the article body. –
