Reports that nearly 800 dead babies were discovered in the septic tank of a home run by nuns [have] sparked calls for accountability from government and Catholic Church officials. Some 796 children were secretly buried in the sewage tank of the home in Tuam, County Galway, where unmarried pregnant women were sent to give birth in an attempt to preserve the country's devout Catholic image. The home was run by nuns from the Bon Secours Sisters congregation between 1925 and 1961. People who lived near the home said they have known about the unmarked mass grave for decades, but a fresh investigation was sparked this week after research by local historian Catherine Corless ... showed that of the hundreds of children who died at the home, only one was buried at a cemetery. She also said that health board records from the 1940s said conditions at the home were dire, with children suffering malnutrition and neglect and dying at a rate four times higher than in the rest of Ireland. The claims came to light after Corless obtained death records for the home and cross checked them with local cemetery records. According to Eoin O'Sullivan, associate professor at Trinity College Dublin, Tuam was a former workhouse and conditions were pretty bleak," said O'Sullivan, co-author of the 2001 book Suffer the Little Children: The inside Story of Ireland's Industrial Schools. "Ireland's first mother and baby home, at Bessborough, in Cork, had an even worse infant mortality rate of around 82 percent: In the year ending March 31, 1944, 124 children were born or admitted there, and 102 died."
