The discovery of infant remains in Tuam, Ireland has shocked the world, revealing a dark chapter in the nation’s history. In 2014, local historian Catherine Corless uncovered evidence suggesting hundreds of babies were buried in a secret mass grave at the former St. Mary’s Mother and Baby Home. This July 2025, excavation work has finally begun at the site, promising answers for families who have waited decades for truth and closure.
The shocking discovery that revealed Ireland’s hidden tragedy
In 2014, an unexpected revelation shook the small town of Tuam in County Galway, western Ireland. Amateur historian Catherine Corless, initially researching her family history, uncovered evidence of what appeared to be a mass grave containing the remains of hundreds of infants and young children. The site was located on the grounds of the former St. Mary’s Mother and Baby Home, an institution run by the Sisters of Bon Secours between 1925 and 1961.
Corless’s investigation began innocently enough with a local history course in 2005. Her curiosity about the “home children” who attended her school separately from other students led her down a disturbing path of discovery. Despite facing resistance and skepticism, she persisted in her research, collecting death certificates for 796 children who died at the institution over its 36-year operation.
The turning point in her investigation came when she spoke with a cemetery caretaker who showed her a grassy plot near a playground in a housing estate built on the former institution’s grounds. He recounted how children playing there in the 1970s had discovered human bones beneath a broken concrete slab. Authorities had allegedly covered the area, assuming the remains dated from Ireland’s 1840s famine.
Through meticulous comparison of historical maps, Corless identified that the area had once been a “sewage tank” that ceased operation in 1937. A later map labeled the same area as a “cemetery.” Despite facing considerable hostility from locals who doubted her findings, Corless’s work was ultimately validated in 2017 when a government investigation confirmed the presence of significant human remains at the site, with ages ranging from 35 weeks fetal gestation to two or three years.
Lives lost and forgotten: the children of St. Mary’s
St. Mary’s was one of several institutions across Ireland where unmarried pregnant women were sent, often rejected by their families due to the stigma of having children outside marriage. After giving birth, these mothers were typically separated from their babies. Many children died from disease, malnutrition, and neglect within the institution’s walls.
According to death records, Patrick Derrane was the first baby to die at St. Mary’s in 1925, at just five months old. Mary Carty, the same age, was the last recorded death in 1960. Between them, 794 other infants and young children died at the institution. Their bodies are believed to have been buried in what former Irish Prime Minister Enda Kenny described as a “chamber of horrors.”
The causes of death recorded for these children reveal the harsh conditions they endured:
- Malnutrition and related conditions
- Infectious diseases like measles and tuberculosis
- Gastroenteritis and other digestive ailments
- Congenital conditions often described in derogatory terms
- Respiratory infections and pneumonia
PJ Haverty, who spent his first six years at St. Mary’s, considers himself fortunate simply because he “got out of there.” He remembers how the “home children” were segregated at school: forced to arrive 10 minutes later and leave 10 minutes earlier than other students, prevented from interacting with them even during breaks. “We were street trash,” he recalls, describing the stigma that followed him throughout his life.
The testimony of Mary Moriarty, who lived in one of the houses built on the institution’s site in the 1970s, provided disturbing eyewitness evidence. After following children who had found a skull, she fell into a hole and saw what she described as “hundreds” of small bundles wrapped in blackened cloths, “stacked one after another, in rows reaching to the ceiling.” Only after giving birth to her own child and seeing how babies were wrapped in the maternity hospital did she realize what she had witnessed.

The search for truth and dignity begins
In July 2025, investigators and excavators have finally begun the painstaking work of excavating the site in Tuam. The operation, expected to last two years, represents a global first in terms of its complexity and sensitivity. Daniel MacSweeney, who heads the excavation and has previously worked recovering missing bodies in conflict zones like Afghanistan, described the unprecedented challenges they face.
The remains are likely mixed together, and the tiny size of infant bones—a baby’s femur is only the size of an adult’s finger—requires extreme care during recovery to maximize chances of identification. “The difficulty of identifying the remains cannot be underestimated,” MacSweeney emphasized.
For people like Anna Corrigan, the excavation represents hope for answers about family members they never knew. Corrigan discovered in her fifties that her mother had given birth to two boys at St. Mary’s: John, who died at 16 months in 1946, and William, whose fate remains uncertain. John’s death certificate listed “congenital idiot” and “measles” as causes of death.
Corrigan, who founded the Tuam Babies Family Group for survivors and relatives, believes that these children have finally been given a voice. “We all know their names. We all know they existed as human beings,” she stated. The excavation will determine the true extent of what lies beneath that patch of grass in Tuam and potentially provide answers to families who have waited decades for truth.
As the work progresses, it stands as a powerful reminder of Ireland’s painful institutional past and the ongoing journey toward acknowledging historical injustices. For the hundreds of children who lived briefly and died at St. Mary’s, this excavation represents a belated recognition of their existence and humanity—a crucial step toward restoring dignity to those who were denied it in life and in death.
