Grace Marks, historical figure (born ca. 1828 in Northern Ireland; date and place of death unknown). Grace Marks was an Irish Canadian maid. She was convicted, along with James McDermott, of the murder of their employer Thomas Kinnear, who was killed along with his housekeeper and mistress Nancy Montgomery in 1843. Marks’s trial was widely publicized in newspapers of the day. Her story has also been told in Susanna Moodie’s Life in the Clearings (1853), as well as in Margaret Atwood’s play The Servant Girl (1974) and her novel Alias Grace (1996). The latter was adapted by Sarah Polley into an award-winning CBC miniseries, starring Sarah Gadon as Marks.
