Ireland's mother and baby home survivors have spent decades fighting for the truth. They can finally see an end in sight  

Survivors of the Tuam mother and baby home hold a vigil for the 973 babies who died at or near the home during its 36 years of operation.

(CNN)Growing up as an adopted child in Ireland in the mid-1960s, Noelle Brown didn't ask questions about her past.  

It wasn't until 2002 that a chat with a friend prompted her to think that it might be time to investigate the circumstances around her birth. 
Brown contacted a charity, which pointed her towards a nun it said could help. But she said the nun dodged her calls for months. When she finally picked up the phone, Brown says she was "rudely" told -- with no further explanation -- that she wasn't entitled to her personal information, but that she could come for counseling.  
    "I took it for granted that all I had to do was ask [for my information]," Brown told CNN. "I didn't realize I was setting off a chain of events that has taken up 20 years of my life." 
      More than 190,000 women and children are estimated to have been placed in mother and baby homes and "county homes" -- institutions where unmarried women were sent to deliver their babies in secret across Ireland for nearly eight decades. 
      Like many of the estimated 57,000 former survivors of those homes, Brown has struggled to find out what happened during her time in one of them.  
      On Friday, the five-year Commission of Investigation into Mother and Baby Homes and Certain Related Matters -- established to investigate what transpired across 14 mother and baby homes and four county homes from 1922 to 1998 -- is set to finalize its report. It's unclear when it will be made public, but the government has said it plans to publish it as soon as possible.
        Survivors like Brown have long hoped that the commission would reveal more about allegations of arbitrary detention, cruelty and neglect, forced adoption and vaccine trials that went on inside the homes, as well as hold wrongdoers to account.
        They also hoped it would help them to access their personal records, including information about missing relatives and babies buried in unmarked graves.
        Now, those hopes have been boosted by a dramatic U-turn from the Irish government on Wednesday evening, less than a week after passing a law that promised to seal the commission's archive from survivors and the public for 30 years.
        Minister for Children and Youth Affairs Roderic O'Gorman had initially said that the law was bound by the Commissions of Investigations Act 2004 "whose purpose is to protect a database created by the commission." 
        But following a groundswell of public opposition rallying against the law, the government changed its position, saying that survivors of the homes are legally entitled to access their personal data.
        Critics of the law had successfully argued that sealing the commission's records was illegal under the General Data Protection Regulation (GDPR), an EU directive which gives individuals the right to access their data. 
        In a statement on Wednesday evening, the government said it "acknowledges and regrets the genuine hurt felt by many people across Irish society," and that it is "determined to take necessary actions to ensure that these concerns are dealt with in a manner that is timely, appropriate and that the focus is on the needs of victims and survivors."
        A conglomerate of groups representing survivors and survivor advocates warmly welcomed the announcement.
        Brown, who was denied access to her own files for decades, is cautiously optimistic. 

        'Emotionally battering' 

        The Bessborough mother and baby home in Ireland's southwest County Cork, seen in 2018.
        Brown was born at the notorious Bessborough home in County Cork. She was adopted into a loving family and grew up just a half a mile away from the home, but more than 900 babies born or admitted to Bessborough died in infancy or early childhood, either there or in a nearby hospital.
        Infant mortality rates there peaked at 82% in 1944, and only 64 of the 900 babies' graves have ever been located. 
        In an interim report released last year, the commission said it found it "very difficult to understand" that no members of the Sacred Hearts of Jesus and Mary the nuns who ran the home, were able to say where the other graves were.
