In the late summer of 1680, the legal apparatus of Argyll directed its attention toward Milnetown, Dunoon, where Issobell McClartich became the subject of formal proceedings. On 31 August 1680, her case was registered under the reference C/JO/2953, marking the beginning of an official inquiry into her conduct. As an inhabitant of the Dunoon area during a period of heightened scrutiny regarding perceived supernatural activity, Issobell found herself caught within the rigorous judicial framework that governed the region at the time.
The subsequent trial, documented under record T/JO/1171, formalised the transition of her case from initial accusation to courtroom examination. Throughout these proceedings, Issobell remained a central figure within the specific administrative records of the Scottish judiciary, which meticulously tracked the movement of her case through the legal system. These archival traces serve as the remaining evidence of her encounter with the authorities of the era, providing a definitive record of her status as an accused individual within the seventeenth-century Scottish landscape.
