 Mary Trembles and Susanna Edwards were investigated after a local woman, Grace Barnes, blamed Trembles for her illness.On 18 July 1682, Mary Trembles was denounced to the authorities and consequently arrested, along with Susanna Edwards, who had accompanied Trembles while they were begging for food (there was a food shortage in the country at the time).At the inquiry, Grace Barnes’s husband John spoke first, accusing Trembles of hurting his wife by witchcraft.
