The funeral for three children found dead in their home will be held on Friday.
Eight-year-old twins Austin and Luke Riggi and their five-year-old sister Cecilia were found in a townhouse in Edinburgh on August 4 following reports of an explosion.
Their mother Theresa Riggi, 46, who is being treated in hospital after apparently falling from a second-floor balcony, has been charged with their murder.
Prayers will be said for the youngsters at St Mary's Cathedral in Aberdeen followed by a private service at the city's crematorium.
An announcement in the Press and Journal newspaper said: "It is with great sadness and grief that we announce the sudden and tragic passing of Austin, aged 8 years, Luke, aged 8 years, and Cecilia, aged 5 years, on August 4, 2010.
"Some people come into our lives and quickly go..... They stay in our lives for awhile, leave footprints on our hearts and we are never, ever the same."
The family requested in lieu of flowers that donations are made to the Reverend Gordon Trust Orphan Fund at the cathedral door or care of St Peter's Church, Justice Street, Aberdeen.
The announcement also said friends, colleagues and parishioners of St Mary's are welcome to attend the funeral mass. A private family service will then be held at Aberdeen Crematorium.
Last week the children's father, engineer Pasquale Riggi, 46, said he was "paralysed with grief" when told of their deaths.
Shell employee Mr Riggi said: "You are not sure what to do next. It is bad enough that you have lost three beautiful children but certainly the tragedy around their deaths makes it much more painful. The reality of it all is difficult to take all at once. You can't even get your head around it."
