A huge thank you to Jessica Allen for captivating a full house with her fascinating presentation on Grace Marks, one of the first women incarcerated at Kingston Penitentiary following the notorious murders of her employer, Thomas Kinnear, and his housekeeper, Nancy Montgomery.
The case became one of Canada's earliest true crime sensations, captivating the public throughout the 1840s. Grace was just 16 years old when she began working for Kinnear in Richmond Hill, where she met farmhand James McDermott. To this day, the mystery remains: was Grace the mastermind behind the murders, or was she an unwilling participant influenced by McDermott?
McDermott was hanged for the crime, while Grace's death sentence was commuted because of her age. She went on to spend nearly 30 years in Kingston Penitentiary before being released in 1872. After her release, she disappeared from the historical record, leaving one question unanswered:
Did she do it—or didn't she? What do you think?
This was our final meeting before the summer break. We look forward to welcoming everyone back on September 23. Until then, we wish you a restful, safe, and wonderful summer!
