In July 1662, Jon Grieve—also recorded in archival materials as Grier—found himself at the center of a judicial inquiry in Lauder, Berwick, amidst the broader context of the Scottish witch trials. As a male defendant, Jon occupied a position within a demographic that accounted for roughly 15 to 20 percent of those accused of maleficium during this period. The surviving records regarding his case are brief but definitive in their progression, marking a transition from the initial proceedings of his case, cataloged under the reference C/EGD/1552, to the formal judicial processes of his trial, documented as T/JO/951.
During that same month of July, Jon provided a confession, a central component in the legal mechanics of the seventeenth-century Scottish courts. While the specific content of his testimony remains lost to history and the final trial notes offer no further details regarding the verdict or the eventual outcome of his proceedings, the existence of a recorded confession indicates that he was interrogated within the rigorous framework of the local ecclesiastical and civil authorities. Consequently, Jon remains a documented figure in the historical landscape of Lauder, representing the formal entanglement between an individual and the legal machinery of the mid-seventeenth century.
