A five-year investigation into mother and baby homes has found an "appalling" level of infant mortality among children born there.
Out of the 18 homes examined by the Commission of Investigation, 9 thousand children died.
56 thousand unmarried mothers - ranging in age from 12 years old to women in their 40s - along with 57 thousand children lived in the institutions.
The Commission says women who gave birth outside marriage were subjected to "particularly harsh treatment" in the period looked at from 1922 to 1998.
It found that was "supported by, contributed to, and condoned by" the institutions of the State and the Churches.
Taoiseach Michael Martin says the report makes often harrowing reading.
While there's been some criticism that the Taoiseach's apology to the Mother and Baby Home survivors tomorrow is too soon, Paul Redmond who was born in the Castlepollard home says he welcomes it.
He was born in the home in 1964 and has written a short history with the information he could find about similar facilities around the country.
Paul Redmond is presently the Chairman of the Coalition of Mother and Baby homes Survivors group.
He hopes the Taoiseach's apology will not refer only to the historic elements of the particular period in history.
