In May 1662, Margret Duff, a resident of the coastal parish of Inverkip in Renfrew, became the subject of a legal proceeding that would see her name entered into the formal judicial records of the Scottish witch trials. Under the case reference C/EGD/1522, official attention was directed toward her activities during a period when the Kirk and local authorities were increasingly preoccupied with the perceived threat of maleficium. The administrative machinery of the time moved with notable speed; having been identified by the authorities, Margret was brought under the scrutiny of the local judiciary during the spring of that year.
By the 7th of May 1662, the legal process against Margret had formalised into a recorded trial. Although the specific trial notes (T/JO/925) have not survived to provide the intimate details of the testimony or the particular accusations leveled against her, the archives confirm that a confession was obtained from her during that same month. This recorded confession marks the final documented stage of her interaction with the justice system, standing as the last preserved element of the account regarding her experience within the early modern Scottish legal framework.
