In the early months of 1662, thirty-one-year-old Agnes Williamsone, a married woman from Sammuelston in Haddington, stood before the High Court of Justiciary in Edinburgh. Her legal ordeal was inextricably linked to the testimony of James Welch, a youth whose denunciations—despite his age preventing him from standing trial—were treated with gravity by the authorities. Agnes found herself caught in a wider web of accusations, named as an accomplice by a significant number of women, including Christiane Deanes, Margaret Baptie, and Elspeth Tailyeor. Throughout the proceedings, the allegations against her were wide-ranging, encompassing property damage to mills, crops, buildings, and stores of meal.
The judicial resolution of her case was complex and reflected the nuances of seventeenth-century Scottish legal practice. On January 27, 1662, the court returned a verdict of "not guilty" regarding the substantive charges brought against Agnes; however, she was simultaneously found guilty "by repute and delation." Following this contradictory outcome, the court postponed her final sentencing, scheduled for February 3. Her case file, preserved in the High Court Books of Adjournal and supplementary draft records, documents a long-standing history of suspicion, noting that confessions had been recorded for her as far back as 1649 and again in May 1661. While her associates were seemingly tried elsewhere in local courts, Agnes remained a singular focus of the Edinburgh judiciary, highlighting the precarious nature of reputation during the intense witch-hunting climate of the mid-seventeenth century.
