In May 1662, Margret Rankin, a resident of the parish of Inverkip in Renfrew, became the subject of legal proceedings concerning the crime of witchcraft. The records indicate that her involvement with the judicial authorities progressed rapidly during that month; she provided a formal confession to the charges brought against her, a development that served as a critical component in the unfolding of her case. This admission was documented shortly before the formal commencement of her trial, which was registered under the judicial reference T/JO/923.
By July 7, 1662, the legal process surrounding Margret had advanced to the stage of a recorded trial. While the specific testimony or narrative details of her case have not survived in the extant records, her progression through the Renfrewshire judicial system reflects the broader patterns of the 1662 witch-hunt in the west of Scotland. Margret remains identified within the historical register by her residence in Inverkip and the formal documentation of her confession, marking a significant entry in the administrative history of the Scottish courts during this period.
