The Catholic Primate of All Ireland and Archbishop of Armagh has made a new appeal for information to help find the remains of six people known as "The Disappeared".
Archbishop Eamon Martin celebrated Palm Sunday mass in Armagh with 17 families who had a loved one killed and secretly buried by republicans during the Troubles.
Since the mid-1990s, ten bodies have been recovered but six bodies remain missing.
A dig for the remains of Joe Lynske, began in a Co Meath bog earlier this month.
Archbishop Martin said some families are living a long Good Friday.
He appealed to the conscience of anyone who has information that might help to come for forward.
His hope is the six affected families could be able to offer a christian burial to their loved ones.
In recent years republicans, through confidential channels set up by the Irish and British governments, gave information that led to the recovery of the remains of several victims.
A mass of remembrance is held each year on Palm Sunday in the College Chapel of Saint Patrick's Grammar School in Armagh to help the families to connect with each other in solidarity and compassion.
