In the late summer of 1649, amidst a period of heightened judicial activity in Haddingtonshire, Marion Lawrie was identified among a group of individuals from the parish of Humbie entangled in the legal processes of the Scottish witch trials. While the archival record remains silent regarding the specific circumstances of her life or the nature of the allegations brought against her, her involvement was part of a larger cluster of legal actions; five other residents of Humbie were listed alongside her in the official proceedings.
On August 15, 1649, Marion provided a confession, a document that served as a pivotal component in the judicial framework of the seventeenth-century Scottish court system. This record was followed the next day, August 16, by the formal registration of her case (C/EGD/1620). Though the surviving documentation from the trial (T/JO/129) does not preserve the substance of her testimony or the eventual outcome of the proceedings, the existence of these records confirms that Marion was processed through the rigorous institutional mechanisms of the time during a year noted for a significant intensification of witch-hunting across the region.
