The removal service for the three brothers found dead in north Cork will take place later.
The bodies of nine-year-old twins Thomas and Patrick O'Driscoll were discovered in their home in Charleville on Thursday evening.
Gardai believe they were killed by their 21-year-old brother Jonathan, before he took his own life.
All three will be reposing at O'Malley's funeral home in New Line this lunchtime, with removal later to Holy Cross Church (4pm).
Their funeral mass will take place tomorrow, but the twins will be laid to rest in a local cemetery, while their older brother will be taken to a graveyard in Kilmallock.
Local priest Father Tom Naughton has known the children since he helped prepare them for their Communion last year.
"The lads were two very fine boys," he said.
"Normal lads for that age - full of life and full of beans. Exploring and mischievous, as you would expect from nine-year-old boys.
"It is a shocking loss."
