Tuam committee have no say on graveyard

My understanding was that they wished to create a memorial to the children who are presumed buried at the site ,and I made a generous donation on behalf of my mother to the committee in memory of my sister who is named as one of the missing children.
I did not realise that they considered themselves the guardians of these children and therefore could assume the right to speak on their behalf.
They do not. It is my wish that the site is exhumed as a matter of urgency. I have never understood why this has not already happened, once it was suspected that the children from the home were there. Catherine Corless’ stirling work has established the fact that these children died there but it is still not known where they are. Only an exhumation can establish the facts.
My mother was denied her child, she was only told the child was dead and discharged from the ‘care’ of the Bon Secours the day her baby died. My mother and sister were treated with great inhumanity and cruelty and denied their basic human rights.
It is not up to the Tuam Graveyard Committee to compound that denial by assuming a role they have no right to.
