Carnmoney, County Antrim, Northern Ireland
Incident period: Fatal household incident in August 1807; assizes in March 1808; later local recollections
A cow gave milk, but the household could make no butter. A woman reputed to undo witchcraft was brought from Carrickfergus to help. By morning, three people were dead inside the house and the would-be healer had barely survived. Mary Butters’s Carnmoney case joins a contemporary newspaper report, a coroner’s finding and a surprisingly mocking local ballad.
The tailor’s household and its missing butter
Alexander Montgomery, a tailor living near Carnmoney Meeting House, owned the cow. The account preserved by St John Drelincourt Seymour says the difficulty was not an absence of milk: it was the failure of repeated churning to produce butter. Montgomery’s wife, Elizabeth, accepted the suggestion that witchcraft was responsible.
The distinction explains why Butters was consulted. She was not accused at the beginning of harming the cow. She was invited to reverse harm attributed to someone else. The episode belongs to the history of people who offered remedies for supposed bewitchment, where the roles of healer, conjuror and witch could change according to the outcome.
Mary Butters comes from Carrickfergus
Butters lived at Carrickfergus and had a reputation for magical assistance. The Dictionary of Irish Biography describes her as a practitioner consulted about cattle and other misfortunes. Seymour’s 1913 account draws explicitly on the Belfast News-Letter of 21 August 1807 and notes preserved by the local historian Samuel McSkimin.
The surviving descriptions do not support a secure birth date. The Dictionary of Ulster Biography’s online display gives approximate dates that sit awkwardly beside the adult woman described in 1807, while other biographies use an earlier estimated birth. This file therefore follows the documented incident and later activity without presenting a guessed lifespan as established personal history.
Two men sent out to the cow-house
At about ten at night, according to the newspaper-derived account, Butters instructed Montgomery and a young man named Carnaghan to stand at the cow’s head with their waistcoats turned inside out. They were to remain until called. The unusual clothing and the separate vigil were part of the operation, not details invented by later ghost tours.
Inside remained Butters, Elizabeth Montgomery, the Montgomerys’ son David and an older woman, Margaret Lee. The two men outside waited until daybreak without receiving a summons. That division of the group became crucial: the men could describe the instructions and the discovery, but not continuously observe what happened in the kitchen.
The discovery at daybreak
Concerned by the silence, Montgomery returned to the house. After no response at the door, the men looked through a window and saw the people lying on the floor. They forced entry. Elizabeth and David were dead; Lee died shortly afterwards. Butters was still alive.
The account describes an offensive sulphurous smell and a pot containing milk and metal items, including pins, needles and nails. It also records Butters being taken outside and physically assaulted by the distraught husband. Her survival does not erase the deaths of the three other people. Their names are central to the case, even though later popular accounts often reduce them to the backdrop of a witch story.
The coroner and the later court outcome
An inquest was held on 19 August 1807. The reported finding attributed the deaths to suffocation associated with the noxious ingredients used in the attempted charm. The Dictionary of Irish Biography identifies coroner James Stewart. McSkimin’s historical account also reproduces the newspaper and inquest material, making it possible to follow where later summaries acquired their wording.
Butters was brought before the spring assizes in 1808 and discharged by proclamation. That outcome is distinct from the inquest’s attribution of responsibility. A coroner’s finding, a charge and a criminal conviction are different stages. The consulted sources do not justify turning the discharge into an execution for witchcraft, nor into a detailed account of a trial whose evidence has not survived here.
The club-bearing stranger in Butters’s account
Butters offered another explanation: a dark figure armed with a large club had entered and attacked the people in the room. The version printed by Seymour attributes the three deaths and her own collapse to this apparition. It is her reported explanation of the disaster, preserved through the later source chain.
The motif gave the incident a supernatural narrative beyond the failed cow remedy. In the inquest account, suffocation linked the deaths to what happened inside the house; in Butters’s explanation, an intruder caused them. Keeping both attributed accounts in view shows the disagreement without replacing the actual finding with a modern reconstruction of the precise chemistry.
The ballad remembers what the prose leaves out
Seymour reprints a long Scots-language ballad from the Ulster Journal of Archaeology for 1908. It describes earlier attempts with rowan and vervain, neighbours gathering to churn, a circle drawn around the churn and the husband waiting beside the cow. Its most important physical detail is the stopping of the chimney and other openings.
The ballad is not a laboratory report or a verbatim deposition. It is satirical, personal and sometimes cruel. Its additional episodes should therefore be identified as the ballad’s account. They show how the locality remembered the incident, including the idea that smoke had been deliberately confined. The prose narrative and the poem preserve related but not identical versions.
A reputation that survived the catastrophe
The poem mocks Butters’s supposed ability to identify thieves and answer questions about lovers, while threatening that she might retaliate against its author. The Dictionary of Irish Biography reports that she continued to be consulted in the area after the case. Neither account suggests that a successful prosecution ended her life in 1808.
That continuation makes Carnmoney unusual among stories grouped loosely as witch trials. Here the central practitioner survived, the charges were discharged and local ridicule coexisted with continued demand for her services. The household tragedy did not simply extinguish the wider belief that some people could diagnose or remove hidden harm.
The historical trail and the mapped locality
The most useful route begins with the August 1807 newspaper reference and inquest, then follows McSkimin, the 1908 ballad printing and Seymour’s 1913 synthesis. The modern biographical entries help identify the sources and the later reputation. They are not additional witnesses to the night in the Montgomery house.
Carnmoney is now within Newtownabbey in Northern Ireland. The map uses a broad locality point because the consulted material does not establish a precise surviving cottage. The case remains substantial without manufacturing one: a named household, an attempted remedy, three deaths, an inquest, a discharge and a local poem that kept the story alive.
