Post-mortem examinations on remains discovered in Co Meath during a search for one of the so-called Disappeared are due to be carried out by State Pathologist Dr Marie Cassidy on Monday.
The bodies of two people, discovered in a field in Coghalstown, Co Meath yesterday, were removed from the scene earlier today.
The discovery was made during a search for members of the so-Disappeared - people abducted, murdered and buried in secret by the IRA.
The search was originally directed towards Joe Lynskey, who disappeared over 40 years ago, and was linked to the site at Coghalstown.
However, as two bodies were discovered in close proximity to one another, authorities now believe the remains may belong to Seamus Wright and Kevin McKee.
The men disappeared from Belfast in 1972, a few weeks after Mr Lynskey, and were murdered and buried in the same area.
The families of Mr Wright and Mr McKee have been told that it should take six weeks to confirm the identities of the deceased.
Mr McKee's sister has said her family will have a huge weight lifted if it is confirmed that her brother's remains have been recovered.
She was nine years old when her brother was abducted and murdered by the IRA.
Ms McKee said she could not explain how much today meant for her family.
She said her mother had lived "in torture" all her life, and had gone to her grave without knowing what had happened to her son.
She said the family had "high hopes" that one of the bodies recovered yesterday would be identified as her brother, and she said they would now be able to move on with the rest of their lives.
Ms McKee said the family had never given up hope of finding his body.
She said they were now feeling a mixture of happiness and sadness, and added that it would mean so much for the family to be able to give their brother a Christian burial.
Ms McKee appealed to anyone with information in relation to the rest of the Disappeared to come forward.
Forty years ago the area where the remains were discovered was wild bog land, but it is now mainly farmland.
The search operation is being conducted by the Commission for the Location of Victims Remains, who have been searching for the remains of Mr Lynskey since March.
The former Cistercian monk was abducted and murdered as a result of an internal IRA feud.
Speaking on RTÉ's Morning Ireland, Lead Forensic Scientist and Investigator with the commission, Geoff Knupfer, said if the remains are not Mr Lynskey's, the search will continue for him in this location.
Mr Knupfer, said it is a huge relief that the bodies "remained intact".
He said the bodies were found lying on top of each other and that they may have been originally buried about a metre underground.
The family of Mr Lynskey visited the site last night.
Family members of Mr Wright and Mr McKee remained at the site today.
Minister for Justice Frances Fitzgerald has said she hoped "the suffering of the families of some of those who were Disappeared over the course of the Troubles in Northern Ireland will now be eased" following the discovery of the two bodies.
In a statement Ms Fitzgerald said the commission will continue to undertake the "humanitarian task" of working to find the "remains of those who have yet to be found".
Both the commission and Sinn Féin president Gerry Adams have renewed their calls for those with information about other Disappeared to come forward.
