We now know pretty well what happened to single mothers in Ireland, up to the 1990s. They were incarcerated in Church-run state-funded, institutions. In these institutions, called mother and baby homes or Magdalene asylums, the women were obliged to carry out hard manual work, to atone for their sins (and provide profits to the institution). Their children were punished too for the sins of their parents. Usually they were stolen from their mothers. Some of the children were secretly sent abroad to be brought up by good Catholic families. Some became sex toys, Some were beaten to death, starved to death, or murdered in other ways. Mortality rates were over four times higher than in the rest of the population.
Now we know a little bit more. In one home at least, children's bodies - almost 800 - were denied a proper burial but instead dumped in a sewage tank. As you might have guessed, the Catholic Church has declined to apologise, or to carry out or assist in any investigation.
