In early 1659, Magdalin Blair of Stirling found herself at the centre of a formal legal process involving the civil and ecclesiastical authorities of her burgh. The scrutiny began in the winter months, marked by a series of denunciations that escalated over several days. On 13 January, an initial statement was delivered to a local minister and a bailie; this was followed by a continuation of the proceedings the next day, and a final report made to the provost and another bailie on 18 January. These denunciations culminated in the generation of a witness list on 16 March 1658, as the judicial machinery prepared to bring her before the justice courts.
Magdalin was subsequently brought to trial on 22 March 1659. Despite the gravity of the accusations brought against her—documented in a case file that appears to have been processed through the North circuit of the justice courts—she remained steadfast throughout the proceedings. When confronted with the charges, Magdalin consistently denied all allegations levelled against her, entering a plea of not guilty. Following the trial, the legal process concluded with a verdict of not guilty, bringing the case to a close.
