Former Fianna Fáil minister Mary O'Rourke has confirmed that the family of the late Brian Lenihan has requested input into the Oireachtas banking inquiry.
Speaking on RTÉ's Morning Ireland, Ms O'Rourke said it is a fact of life that one of the main figures in the committee's deliberations who cannot be with them is her nephew, the late Mr Lenihan.
She said it has struck her forcibly "that those to whom he may have confided in on some matters should be given a chance to come before the committee to speak their mind".
"We wish to put the committee under notice that we will be following events and listening to what the witnesses will be saying internally about the late Brian Lenihan and we wish, if necessary, to render the recommendations of the committee more complete."
While she added that she has no desire to appear before the committee, she hopes that Conor Lenihan, who was a minister of state at the time, would be able to do so if required.
She said she does not have papers or records belonging to Brian Lenihan; he did confide in her on many things, as he did to Conor Lenihan.
"I do not have papers or records but I have a memory. I am lucky that it is a good memory."
She refused to comment on reports that Brian Lenihan had argued that Anglo Irish Bank and Irish Nationwide should be nationalised instead of being included in the State guarantee of 2008.
On Friday, former taoiseach Brian Cowen said there was "no question" that he had overruled Brian Lenihan on this.
Ms O'Rourke said it may emerge in the evidence that will be given by Mr Cowen to the committee, and possibly be amplified.
She said that they will be watching those matters very carefully.
