Isobell Houston, a resident of Houston, Renfrew, found herself embroiled in the turbulent and perilous world of witchcraft accusations at the dawn of the 18th century. As a married woman with dairy cows, Isobell's life took a dire turn when she was denounced by young Margaret Laird of Paisley. Margaret, in the throes of convulsions, accused numerous individuals of witchery, including Isobell. Such cases were not uncommon as women and men alike were frequently implicated as witches due to the superstitions and fears prevalent in Scottish society at the time.
The testimony presented against Isobell originated primarily from these fits and the fervent statements made in Paisley during April 1699. Despite the severe nature of the accusations, which included alleged damage to her dairy property, the charges appeared tenuous and were predominantly based on the dramatic and volatile declarations made by Margaret Laird in her agitated state. The trial was scheduled to occur in Glasgow in May 1699 but did not proceed as planned, and eventually, the case moved to the high court in Edinburgh.
On 12 March 1700, Isobell was released after the diet was deserted in the high court. The case against her did not hold, as evidenced by the lack of a formal trial and sentence following the initial diet arrangements. Isobell’s release suggests an absence of decisive evidence or overwhelming suspicion to compel the court to proceed further with the prosecution. Thus, she returned to her life in Houston, the shadow of the witch trials looming but, notably, without a legal conviction marring her name.
