In the early months of 1659, Marion Angus, a resident of Stenton in Haddington, became the subject of intense legal scrutiny as part of a wider series of witchcraft allegations circulating in the region. Her involvement was cemented by the testimonies of four other women—Janet Wood, Helen Heriot, Jean Sydserff, and Bessie Lacost—all of whom denounced Marion during their own legal proceedings. By February 21, 1659, these accusations culminated in a trial held by Justices of the Peace, a session formally inaugurated by the fencing of the court. Notably, the judicial process deviated from the customary reliance on a jury; instead, the Justices themselves proceeded to reach a verdict of guilty.
Following this conviction, Marion was moved to the Tolbooth, where she provided a confession on the same day the trial concluded. Although an indictment was drawn up against her, its contents remained undated. The final stage of her legal journey saw her transferred to Edinburgh on March 1, 1659, in accordance with the Justices' orders for her sentencing. Her case remains documented in the archives under C/EGD/311, serving as a distinct record of the administrative and judicial mechanics that governed the prosecution of witchcraft in mid-17th-century Scotland.
