Background and detail
Background. The "Black" Donnellys were Irish Catholic immigrants who settled in Biddulph Township in the 1840s. Their presence on a concession road known as the Roman Line created friction in a predominantly Protestant area. Longstanding violent feuds with neighbors culminated in a vigilante mob attacking the homestead on February 4, 1880.
Community Tensions. Tensions escalated in 1879 when a militant splinter group of the Peace Society, known as the Vigilance Committee, began covert meetings. This group, including Constable James Carroll, held grievances against the Donnellys for violating social codes. The committee gathered at the Cedar Swamp Schoolhouse on the evening of February 3, 1880, before proceeding to the homestead.
Immediate Aftermath. The mob killed five family members and burned the farmhouse. William Donnelly survived and served as the informant on death certificates dated April 1 and 2, 1880, listing the cause as "supposed to be murdered." Preliminary hearings began in February 1880, though the scope of this record excludes subsequent trials.
