The Sisters of Mercy became aware of allegations of abuse in the late 1980s and early 1990s. Sr O’Neill stated: It was at that time that we became aware of the pain that some people who had been in our institutions were still carrying in their adult life as a result of their time there. That we became aware of mainly through the public domain. Through books that had been published. I refer to the book "The God Squad" in the late 80s and "You May Talk Now" by Mary Phil Drennan. They were people whose stories related to institutions that were run by our Congregation.
