Margaret Watsoun, a resident of Carnwath in Lanarkshire, was caught within the intensifying judicial scrutiny of the mid-17th century. Her connection to the broader community of the accused was familial, as she was identified as the niece of another woman who also bore the name Margaret Watsoun. The legal proceedings against her were deeply interconnected with those of her peers; during the cycle of trials, she was named as an accomplice by several other women, including Helen Stewart, Kathren Shaw, Maillie Pattersone, Jonet Lockie, and her own aunt, Margaret Watson.
The judicial process culminated on 31 December 1644 in Lanark, where Margaret faced charges that included participating in a witches’ meeting. These accusations followed a confession she had provided months earlier, on 29 September 1644. Upon the conclusion of the trial in Lanark, the court returned a verdict of guilty, marking the end of the documented proceedings against her.
