In July 1649, Margrat Vaith, a resident of Haddington, became the subject of a formal legal proceeding regarding the crime of witchcraft. Her case, documented under reference C/EGD/1338, moved rapidly through the judicial system of the era. Within the span of a few days, Margrat was subjected to formal questioning within the confines of the Haddington Tolbooth, where she provided recorded confessions on two separate occasions: first on the 13th of July and again on the 16th of July.
The broader context of the investigation suggests that Margrat was not viewed in isolation, as her involvement was explicitly linked to others within the local judicial network. Specifically, she was named as an accomplice by Margarit Robertson during the course of Robertson's own trial. Following these recorded examinations and testimonies, the legal process concerning Margrat culminated in a trial, indexed as T/LA/1023, which took place on the 18th of July 1649.
