Mary Gallagher, the Ghost of Griffintown

The story

Griffintown is a district in the Sud-Ouest borough of Montreal, built up in the nineteenth century around the Lachine Canal and settled largely by Irish workers. It has changed enormously. According to Wikipedia, the district emptied in the decades after the Second World War, and the Irish parish church of St. Ann was demolished in 1970. This entry follows one woman rather than the district.

Mary Gallagher was killed and beheaded on 27 June 1879, in a house on William Street. Wikipedia says she was allegedly a sex worker. Her age is unclear: Vice gives about 60, then 38 according to her husband. Vice quotes the Montreal Weekly Witness and the inquest testimony, and a podcast on the case lists the Witness of 2 July and the Globe of 30 June 1879. We did not read these papers ourselves.

A coroner's inquest is dated 7 July 1879 in a case styled The Queen vs Susannah Kennedy, Michael Flannagan and Jacob Mears, according to photograph captions in a podcast on the case. Susan Kennedy was found guilty, with a recommendation for mercy, and sentenced to hang on 5 December 1879. The sentence was commuted and, according to Vice, she was freed after sixteen years. Michael Flanagan drowned in the Peel Basin on 5 December, again per Vice. Globe pieces on the case are listed for 8 July, 6 October and 6 December 1879, also unread. The murder is therefore well attested, even if only through later accounts and press titles; the ghost is another matter.

The legend

The ghost tale says that Mary Gallagher appears without her head every seven years, on 27 June, near William Street, looking for it. Parents in the Irish community are said to have used the story to frighten children and to preach temperance, according to Vice and Concordia University's news site.

We could not find where this legend came from. Vice says only that locals soon began to report the ghost and that the seven-year tradition arose eventually, with no dates. The oldest dated trace we found is a Montreal dispatch in the Indianapolis Times of 30 October 1928 (page 1, read as scanned text only). It describes a ghost of Griffintown first reported as a shapeless phantom and then as a headless woman, met on William Street by a witness who also gave it what the scan seems to read as an axe. It does not name Mary Gallagher and says nothing of 27 June or of a seven-year cycle, so the link with her is our inference. Alison Loader, an artist who taught at Concordia (reported in 2011), observes that local historians all draw on the same newspaper articles of the time; she is speaking of the facts of the case, not of the ghost. Vice relies on Alan Hustak, whose book The Ghost of Griffintown appeared in 2005, for its ghost accounts. A 2016 piece from Quebec's national library, BAnQ, titled "Les origines d’une légende irlandaise…montréalaise!", is listed by the podcast; its site did not respond to us and we did not read it.

The one named witness we have is Denis Delaney. According to Vice, he told Hustak that he had seen her three times and that in 1956 she pointed him toward a necklace. That is a late oral account passed on by an author, and Hustak himself told Vice that Delaney drank a lot and had a great imagination. A Wikipedia page on the district puts the last reported sighting in 1928, which contradicts the 1956 story, though the 1928 press item shows that a headless ghost was in the news that year; we could not resolve it. The same Wikipedia text also mentions a Mary Gallagher Day each 27 June every seven years.

In modern media, a 2003 documentary by Richard Burman called Ghosts of Griffintown (as listed on Wikipedia, which we have not checked) uses her story as a metaphor for the community's disappearance. Hustak's book followed in 2005. The artist Alison Loader worked on the story in 2011, and the Gazette's Bill Brownstein wrote about it on 26 June 2019. In short, the murder was reported in 1879, a headless ghost on William Street was in the press by 1928, and the oldest dated item we found for the full tale of the seven-year return is that 2003 documentary, known to us only through Wikipedia.

What remains today

Vice described the site of the murder house in 2017 as an empty lot, and the district is heavily rebuilt. Wikipedia says the site of St. Ann's Church is now a park where parts of the foundation can be seen and benches stand where the pews were, which is a trace of the Irish parish and not of the case. A Montreal Times notice announced a vigil by a ghost-tour company for 27 June 2019, CTV News reported a tour and related events for 27 June 2026, and Concordia's 2011 piece expected her in 2012, so the cycle as now told runs 2012, 2019, 2026. That date has passed for this year. Adding seven years to 2026 gives 2033, but that is our own calculation from the legend's cycle, not an announced event.

Visiting

Griffintown is an urban district, and you can walk its public streets; Wikipedia describes the park at the former church site. Nothing remains of the murder house that we could confirm, and we found no recent documented sighting, so go for the history of the district, not for a sighting. Be considerate of anyone living or working nearby. If a 27 June gathering is organized, check local listings. To go further, the Vice article, the Concordia news story and the podcast episode in the sources below are the accounts we read (the podcast only in part), and Hustak's book, which we did not read, is the main source for the ghost tales.
