In the spring of 1662, the village of Samuelston in Haddington became the focus of intense judicial scrutiny as part of a significant wave of prosecutions that swept through the region. Among those drawn into the legal proceedings was Issobell Thomsone, whose fate became inextricably linked to the testimony of a local youth named James Welch. Welch had provided a series of denunciations that the authorities took with considerable gravity, despite his young age preventing him from standing trial himself. Following his confession and the naming of several individuals, Issobell was identified as one of those implicated in his account.
Issobell was subsequently brought before the authorities to answer for these accusations, with legal documentation recording her case under reference C/EGD/528. As the judicial process unfolded, her matter proceeded to formal trial phases, documented under the references T/JO/1832 and T/LA/1326. While the specific outcomes of these hearings remain tethered to these archival records, her inclusion in the proceedings highlights the complex legal mechanisms employed during the height of the 1662 investigations, where the testimonies of even the youngest witnesses were sufficient to initiate the formal machinery of the Scottish courts.
