The "Black Donnellys" were a family of Irish settlers to Ontario. Five members of the family were murdered by an armed mob in the township of Biddulph in February 1880 and their farm was burned down, the culmination of long-standing conflict between the family and other residents. No-one was ever convicted of the murders, despite two inconclusive trials
