In April 1630, legal proceedings were initiated against Margaret Heriot, a resident of the Carrington Walkemylnes in Midlothian, regarding allegations of witchcraft. The records from the High Court of Justiciary (C/EGD/1205) formalize the commencement of her case on the 21st of that month. Her situation was part of the broader legal landscape of early modern Scotland, where accusations brought before the authorities were subject to specific judicial protocols, eventually leading to her trial under the reference T/LA/759.
As the matter transitioned into a formal trial, Margaret faced the scrutiny of the Scottish legal system of the early seventeenth century. The records identify her specifically by her location at the walkmills of Carrington, placing her within the industrial and agricultural social fabric of the parish. Though the surviving documentation is brief, it marks the pivotal involvement of state and judicial machinery in her life, reflecting the structured manner in which the Scottish courts managed these accusations during the period between 1563 and 1736.
