In 1807 in the Presbyterian community at the townland of Carnmoney, County Antrim, an interesting case arose. A tailor by the name of Alexander Montgomery and his wife Elizabeth found that they were unable to make butter from the milk they took from their only cow.
Elizabeth enquired with some of the older women in the area who explained that this was not an unusual occurrence, and all had heard stories of this happening before. They offered a couple of suggestions of countermagic that would help, including tying Rowan (also known as Mountain Ash) branches to the tail of the cow and hanging another talisman in the animal’s enclosure/byre. When this failed, they got twelve women to pray around the cow and fed it vervain (a herb with magical association).
When these measures failed the women suggested enlisting the help of a local wise woman with supernatual power who specialised in curing bewitched cattle (but also dabbled in telling fortunes, finding stolen horses, and using divination).
Mary Butters was sought out and brought in to try and rectify the issue. Mary was born in Carrickfergus, a town famous for another high-profile witch trial featuring the ‘Islandmagee Witches’ roughly a century before. She tried various remedies including trying to churn the butter herself while whispering an incantation, as well as drawing a circle around the churn and washing it out with south-running water.
When these failed she instructed Alexander and another local boy to turn their waistcoats inside out and to go stand guard at the head of the cow and not move until she returned to them at midnight. She entered the house with Elizabeth, Elizabeth’s 20-year-old son David, and their elderly lodger Margeret.
She blocked up the windows, doors, and chimney and took out a large pot/cauldron. Into this, she placed sulfur, milk from the cow, and some large iron nails and crooked pins.
This countermagic relied on sympathetic magic in which the cauldron represented the bladder of the witch who cast the bewitchment. As it was heated it would cause tremendous pain in the target.
Blocking up the windows and doors prevented them from entering the house and knocking over the pot/cauldron and breaking the counterspell. The pain would cause the person to subsequently break the original bewitchment on the animal.
Mary placed the pot on the fire and began the proceedings. Midnight came and went and as the hours passed on Alexander became worried and made for the house. He kicked the door in and found his wife and son dead on the floor with Mary and Margeret barely clinging to life.
They were carried outside but Margeret died a few minutes later, with Mary coming round soon after. One source claimed that Mary was brought back to her senses after being thrown on a dungheap and beaten by the husband and some locals, although this appears to not be true.
The inquest was carried out on the 19th of August 1807 in front of 12 jurors. All deaths were declared as accidental due to suffocation as a result of the sulfurous fumes due to Butters’s ritual. A trial was held in 1808, but this was discharged by a grand jury.
An unpublished 19th-century memoir by W.O. McGraw claimed that there was more to Butters’s actions than met the eye. He claimed that she did it on purpose to murder Elizabeth and her son who allegedly had been instrumental in the conviction and subsequent execution of a relative of Mary Butters in 1803 for spreading messages of rebellion.
According to the source, Mary had insisted that the son, who was married and living miles away, be part of the ritual. It also claims that she had on multiple occasions tried to force Margeret to not take part in the ritual and that it would be of great cost to her if she did. None of this however was included in the trial, not to mention the ritual (including the use of sulfur) was widespread. As such these claims appear unsubstantiated.
Mary appears to have moved from Carrickfergus to Carnmoney following the ordeal and continued to be hired by the locals for many magical services for decades following the incident. The excerpt of the poem at the beginning of this article is a contemporary poem and is the possibly only extant poem we have relating to Irish witchcraft.
