What Is a Banshee?

A banshee is a supernatural woman in Irish folklore whose cry announces that someone connected to a particular family is dying or has died. She is often called a death omen, but that description can make her sound like the threat. Traditionally, she doesn’t murder the person, choose the victim or arrive to collect a soul. She mourns. The horror lies in hearing grief before you know whose grief it is.

You may picture a floating hag unleashing a glass-shattering scream. Modern horror has been very fond of that version, understandably enough. Older Irish accounts are less tidy. The banshee may be heard but never seen, or glimpsed as a young woman, an old woman or a figure combing long hair. Her sound may be a shriek, a low lament, a sobbing cry or something that seems to travel around a house without coming from any ordinary direction.

Most of all, she belongs to relationships. Banshee traditions are tied to kinship, inherited memory and the unsettling moment when private loss seems to announce itself across a landscape. To understand her, it helps to set aside the idea of a generic screaming ghost and listen to what the stories actually say.

The woman in the name

The English word banshee comes from the Irish bean sí. Bean means woman, while sí connects her with the otherworld and the ancient mounds associated with its inhabitants. The New English-Irish Dictionary from Foras na Gaeilge gives bean sí as the Irish term. You will also see the older spelling bean sídhe in English-language books.

Calling her a fairy woman is reasonable, provided that fairy isn’t reduced to a tiny winged person living in a flower. The Irish sí belongs to the much broader and often dangerous world explored in our guide to fairies and the fae. Yet the banshee has a specialised place within that world. She is usually solitary, closely attached to human families and defined by her warning cry rather than by the bargains, thefts and exchanges found in many other fairy traditions.

A warning rather than an attack

The banshee’s appearance means death is near, but the stories don’t usually make her its cause. She is closer to a messenger and mourner than a killer. That difference changes the emotional shape of an encounter. There is no monster to defeat and no bargain that will make the message go away. By the time the cry is heard, the event it announces may already be beyond anyone’s control.

Some accounts place her outside the family home shortly before news arrives from elsewhere. This allowed the tradition to speak to a familiar historical fear. A relative could die on a journey, at sea, in war or after leaving Ireland, while the people at home had no quick way to know. In the story, the family hears first. The formal message catches up later.

Other tellings say she cries at the death itself, or continues over several nights while a person is ill. The timing varies because this is a body of local and family traditions, not a timetable maintained by a particularly gloomy civil service. What remains steady is the connection between her voice and a death within the kin group.

The cry sounds like mourning

The word scream catches only part of what people described. Banshee accounts speak of wailing, moaning, crying and keening. The sound can begin softly and rise, or seem unbearably loud from the start. Sometimes it resembles a woman’s voice. Sometimes witnesses compare it to an animal while insisting that no familiar animal sounded quite like it.

That voice belongs beside the Irish tradition of caoineadh, or keening. Human keeners performed vocal laments for the dead, giving grief a public sound through sung words, cries and improvised praise. An RTÉ Archives feature on keening in Ireland describes it as a sung poem that remembered the person who had died. The banshee isn’t merely a human keener with supernatural lighting, but the resemblance matters. One mourns after death within the funeral gathering. The other is said to mourn before the household fully understands what has happened.

This connection also explains why reducing the banshee to a loud noise loses so much. Her cry isn’t frightening only because it is piercing. It is recognisable as sorrow, and sorrow usually has a name attached even when the listener doesn’t know it yet.

The families she follows

Popular summaries often claim that banshees belong only to a short list of old Irish surnames, usually names beginning with Ó or Mac. There is a historical reason for associating the tradition with Gaelic family lines, but the neat list is far less dependable than it looks. Oral accounts connect banshees with numerous families, and those families change names, branch out and marry into others.

A story collected in County Leitrim during the 1930s makes the problem wonderfully clear. In the Schools’ Collection preserved by Dúchas, an older farmer told of Mary Anne Cox, who was abandoned before her wedding by Peter McNally. In her grief, she vowed to cry after his friends. The account presents this as the origin of a banshee that later cried for descendants of the Cox and McNally families.

The storyteller then acknowledges a very practical complication. The Cox family spread widely, while generations of intermarriage meant McNally descendants came to be known by other surnames. This is not an ancient master key to all banshee lore. It is one local origin story, shaped around remembered names and a broken engagement. Its value lies in showing how flexible family attachment could be. The banshee followed descent and relationship, not a printed surname chart.

Young woman, old woman or no woman at all

There is no single authorised portrait. In some places the banshee is an old woman with loose grey or white hair, dark clothing and a face marked by mourning. Elsewhere she is tall and young, with pale skin, red or golden hair, and a white or green garment. She may crouch under a window, stand by water, move through a field or sit on a wall combing her hair.

Many witnesses never claim to see her at all. Illustrations have made her body seem more fixed than the oral tradition does. A disembodied cry can remain uncertain. Once an artist gives it claws, a skull-like face and a billowing dress, the mystery has acquired a costume department.

The comb is one of her best-known objects. Stories warn against picking up a comb found on a road, wall or bank because it might have been left by the banshee. In some versions, she comes to the house to reclaim it, and returning it with iron tongs is the safest approach. These are not universal rules for surviving an encounter. They belong to a particular strand of the tradition in which loose hair, combing and lament are closely joined. Even without supernatural concerns, leaving an unexplained comb where you found it remains a fairly painless policy.

A cry remembered in Galway

The Schools’ Collection also preserves short statements that feel closer to community memory than polished legend. A record from Gort an Iomaire in County Galway names the Heagney and Madden families as families for whom the banshee cried. It adds that the banshee had been heard when a member of the Madden family died in 1930.

The Gort an Iomaire record gives no moonlit chase and no detailed apparition. It places the belief among funeral customs such as wake candles, the position of the body and the route out of the house. That setting is revealing. For the person recording it, the banshee wasn’t an isolated fantasy creature. She belonged to the same practical world of family death, wake arrangements and remembered local behaviour.

The archive documents that this belief was reported. It cannot establish what produced the sound or whether the event happened exactly as remembered. Folklore records preserve testimony, and testimony tells us what a community repeated, feared and recognised. That is already a considerable piece of history without asking it to serve as laboratory evidence.

The woman at Lady Fanshawe’s window

One of the most frequently retold early encounters appears in the memoirs of Ann, Lady Fanshawe. During the upheavals of 1649, she and her husband stayed for three nights with Lady Honor O’Brien in Ireland. At about one in the morning, Fanshawe wrote, a voice woke her. In the moonlit window she saw a pale woman dressed in white, with red hair and what she called a ghastly complexion.

The woman spoke three times in an unfamiliar tone, seeming to say “A horse,” then vanished with a sigh like wind. The household later told Fanshawe that an O’Brien relative had died at two that morning. Lady Honor explained that a woman’s shape appeared at the window when members of the family were dying and supplied a local story about a murdered woman whose body had been thrown into the river below.

You can read the episode in Fanshawe’s own Memoirs of Lady Fanshawe, written later in the seventeenth century. It needs careful handling. Fanshawe never calls the apparition a banshee, and her comments about Irish superstition reflect the religious and English assumptions she brought with her. Later writers fitted the episode into banshee history because it combines a female apparition, an old family and an announced death. It is a valuable early parallel, but calling it the first verified banshee sighting would promise far more than the memoir can deliver.

The landscape carries the news

Banshee stories often place the cry at boundaries. It comes through a window, from beneath a bridge, beside a river, across a bog or along the wall enclosing a property. These are good settings for an ambiguous sound, but they also join household and landscape. The death may occur far away while the warning arrives at the family place, as if land and kin remember one another.

Night makes the source hard to locate. Wind shifts, animal calls carry and a distant human voice can seem unnervingly near. Foxes, owls, cats and other animals have all been offered as explanations for supposed supernatural cries. Such possibilities can explain individual experiences without explaining the entire tradition. A strange sound becomes a banshee encounter only when listeners already have a story that connects it with a family, and when a later death gives the memory its terrible ending.

The Scottish washer is not the same woman

Scottish Gaelic tradition has its own female death messenger known as the bean nighe, or washerwoman. She is encountered washing bloodstained clothes at a stream or ford, and the garments are understood to belong to someone approaching death. The family banshee and the washer share Gaelic language, female mourning imagery and knowledge of death, so comparing them is worthwhile.

They should not be folded into one creature. The Irish banshee is chiefly known by her cry and her attachment to a family. The Scottish washer is defined by the act of washing and by an encounter at water, and stories may give a witness ways to approach or question her. Related traditions can remain distinct, much as neighbouring families can share features without becoming the same family.

When the wail became a weapon

Popular culture tends to turn passive warnings into active powers. Marvel’s Irish mutant Banshee, Sean Cassidy, converts the famous cry into a sonic ability that can attack enemies and carry him through the air. The name gives the character an immediate Irish identity, but the direction of power has reversed. A folkloric banshee announces harm she doesn’t cause. The superhero’s voice causes physical effects on command.

Martin McDonagh’s 2022 film The Banshees of Inisherin goes in another direction. There is no conventional shrieking spirit stalking the fictional island. Instead, the title fills the story with anticipated loss, while the elderly Mrs McCormick predicts death and watches the characters with unnerving calm. A Golden Globes feature on the film’s folklore identifies her as its banshee-like figure. She doesn’t need to howl because the whole island has begun to sound like a lament, from a friendship breaking apart to civil war heard across the water.

Between the superhero and the film lies the modern range of the word. A banshee can now mean an attacking screamer, a sonic power, an omen or a metaphor for grief. Those reinventions keep the name familiar, though they can hide the quieter dread of the traditional figure.

The worst part is knowing

The banshee endures because she gives advance form to a fear that cannot be fought. News of death changes a family in an instant, yet the stories imagine that grief has already been moving toward the house. It passes over fields, stops below a window or rises beside the road before anyone dares to say a name.

That makes her more intimate than a wandering ghost. She knows which family she has come for, even when the people listening do not. Her cry is not a threat of what she might do. It is the sound of something already happening, and there may be nothing left to do except wait for the knock at the door.
