In December 1629, the judicial records of Peebles formally identified Sussanna Elphinstoun as a subject of investigation within the context of the Scottish witch trials. Her name appears in the archival documentation under case reference C/EGD/660, which signifies her inclusion in a larger, complex legal proceeding involving twenty-six other individuals. This collective indictment underscores the common practice during this era of grouping suspects together when accusations emerged from within a specific community, often suggesting a perceived network of illicit activity linked to localized social or religious anxieties.
Despite the breadth of the initial investigation, further archival evidence remains sparse. The subsequent entry regarding her trial, indexed as T/JO/552, provides no additional narrative detail concerning the specific charges brought against her, the nature of the testimony provided, or the final resolution of her case. As such, Sussanna remains a figure defined by her presence in the formal registers of the seventeenth-century Scottish legal system, representing one of many lives caught within the machinery of a judicial process that sought to identify and adjudicate the crime of witchcraft across the region.
