On May 22, 1649, Margaret Gibson, a resident of Tranent in the Haddington region, became the subject of a formal legal inquiry regarding allegations of witchcraft. Her case, documented under reference C/EGD/1615, unfolded during a period of intense judicial scrutiny concerning occult activities within the Scottish Lowlands. Following the initiation of these proceedings, Margaret was brought to trial under the designation T/LA/1960 to address the charges leveled against her by the local authorities.
The historical record confirms that Margaret provided a formal confession during the course of the proceedings. While the specific content of her testimony remains confined to the archive, the existence of this record indicates that she engaged directly with the judicial process as it was constituted at the time. Through this admission, the case against Margaret moved toward its resolution within the established ecclesiastical and civil frameworks governing early modern East Lothian.
