The father of Carla , Darragh and Conor McGinley says the family will be "forever heartbroken" following their deaths.
A Mass of the Angels has taken place in Rathcoole for the siblings, aged three, seven and nine, who were murdered in their home in Dublin last Friday.
Andrew McGinley has thanked Lego, Marvel, Frozen and the inventor of the trampoline for the joy they brought to his children's lives.
He told mourners that he still had promises to carry out for each of the children:
''I have promises that I have to keep and this will drive me on.
''Conor announced at Christmas that he wanted to set up a YouTube channel. Containing what he never quite committed to but I promised to help him and I will do that for him.
''I promised Darragh that I would coach at Rathcoole Boys so apologies to the club, you may never get me out of there from mow on.
''And I promised Carla a snowman, the place will be filled with snowmen every time it snows''.
In finishing a very emotional eulogy, he said:
''We often misuse words. When Ireland would lose a match, I used to say I was heartbroken.
''I now know what that truly means. We as a family are heartbroken
''It will only be with your help, support and friendship that we will be able to patch our hearts together in some way.
''But we will still be forever heartbroken.
''Connor, Darragh Carla, I love you, I love you, I love you.''
Fr Kevin Doherty told mourners: “Their very going from us has left a chasm of absence in our lives.
“It is like a pall of darkness, a shroud of darkness, has come down upon us, and no-one is left untouched.
“This darkness has come into our communities, in Newcastle and in Rathcoole.
“It has come to our schools, where children are confused and fragile and questioning ... and our wonderful teachers are speaking, out of their own sadness, gentle love to these children.”
43-year-old Deirdre Morley, the children's mother, has been charged with their murder.
