Fresh evidence has been uncovered of neglect at a Protestant-run institution in Dublin.
Research has found that one child died every three weeks at the Bethany Home in Rathgar from 1935 to 1940.
The number of unmarked graves of children from the home had thought to number 40, but new evidence published in the 'History Ireland' magazine says it is five times that number.
In May at Mount Jerome cemetery, a group of Bethany's ageing survivors mourned the deaths of 40 of the home's child-inmates in 1935 and 1936.
Niall Meehan, who identified the occupants of those unmarked graves, today publishes evidence of 179 more such resting places dating from the period 1922 to 1949.
Mr Meehan claims that when a Catholic charity alleged neglect, the State suppressed health needs and forced the home to stop admitting Catholics.
He also reports that Minister Dermot Ahern's Secretary had written to him saying that in 1945 the Department of Justice designated the home as a place of detention for female Protestant children and young persons.
A Survivors' representative has written to the Taoiseach that this gives the lie to the Department of Education's claim that children were in the home in a voluntary capacity and therefore do not qualify for payments under the Residential Institutions Redress Scheme.
Survivors say the disclosure strengthens their case to be compensated under the State's Redress Scheme.
