In the summer of 1661, Janet Daill, a 39-year-old married woman from Musselburgh in the parish of Inveresk, found herself drawn into the legal machinery of the Scottish witch trials. Janet, whose husband worked as a collier, had lived with a reputation for alleged witchcraft that had persisted for fourteen years within her community. By early July, the formal process of the court had begun to close in on her, and on July 8, 1661, she provided a confession that would serve as the basis for the proceedings against her. Her case appears to have been intricately linked to a wider network of accusations, as she was identified as an accomplice by several other individuals facing trial at the time, including Agnes Johnston, William King, Margaret Bell, Agnes Andersoun, and Margaret Barbor.
Following the documentation of her confession, Janet was brought before a court in Edinburgh on July 29, 1661, to face charges that included attending witches' meetings. The legal process moved with a swift and stark finality; the court returned a verdict of guilty on the same day as her trial. The sentence was carried out the following morning, on July 30, 1661. In accordance with the judicial practices of the era, Janet was executed by being strangled and burned.
