In the winter of 1644, the legal machinery of Lanark turned its attention toward Jean Lachlane, a resident of Carnwath. The proceedings against her were initiated in the final months of that year, culminating in a recorded confession on September 29, 1644. While the specific nature of her testimony remains confined to the judicial archives, the records indicate that she faced charges relating to a "witches' meeting," a category of accusation that frequently appeared in the Scottish courts during this period of intense religious and social anxiety.
Following the initial confession, the trial of Jean proceeded through the local court at Lanark. By December 31, 1644, the legal process had reached its conclusion, with the court delivering a verdict of guilty. Shortly thereafter, on January 2, 1645, the sentence was carried out. The historical record confirms that Jean was executed, marking the finality of the judicial proceedings conducted against her within the jurisdiction of the Lanarkshire authorities.
