Everyone remembers the chill of horror they felt when, in March 2017, it was revealed that the remains of many small children had been found beneath a playground in Tuam. The discovery was due to the tireless work of local historian Catherine Corless, whose research had uncovered a strange anomaly in the records of the Bon Secours Mother and Baby Home that had existed on the site: there were death certificates for 796 babies and toddlers, but no burial certs. It turned out that a number of the children had been interred without record in an unused septic tank.
