DUBLIN — A mass grave containing the remains of babies and young children has been discovered at a former Catholic orphanage in Ireland, government-appointed investigators announced Friday in a finding that offered the first conclusive proof after a historian's efforts to trace the fates of nearly 800 children who perished there.
The judge-led Mother and Baby Homes Commission said excavations since November at the site of the former Bon Secours Mother and Baby Home in Tuam, County Galway, had found an underground structure divided into 20 chambers containing "significant quantities of human remains."
The commission said DNA analysis of selected remains confirmed the ages of the dead ranged from 35 weeks to 3 years old and that they were buried chiefly in the 1950s, when the overcrowded facility was one of more than a dozen in Ireland offering shelter to orphans, unwed mothers and their children. The Tuam home closed in 1961.
Friday's findings provided the first proof after decades of suspicions that the vast majority of children who died at the home had been interred on the site in unmarked graves. That was a common, but ill-documented practice at such Catholic-run facilities amid high child mortality rates in early 20th century Ireland.
The government in 2014 formed the investigation after a local Tuam historian, Catherine Corless, tracked down death certificates for nearly 800 children who had died as residents of the facility — but could find a burial record for only one child.
"Everything pointed to this area being a mass grave," said Corless, who recalled how local boys playing in the field had reported seeing a pile of bones in a hidden underground chamber there in the mid 1970s.
The government's commissioner for children, Katherine Zappone, said Friday's findings were "sad and disturbing." She pledged that the children's families would be consulted on providing proper burials and other memorials.
"We will honor their memory and make sure that we take the right actions now to treat their remains appropriately," Zappone said.
The report found that the dead children may have been placed in underground chambers originally used to hold sewage. Corless said she found records stating that the sewage systems were used until 1937, when the home was connected to a modern water supply.
A decommissioned septic tank had been "filled with rubble and debris and then covered with top soil" and did not appear to contain remains, the report said. But excavators found children's remains inside a neighboring connected structure that may have been used to contain sewage or waste water.
