The funerals will take place next week for a couple and their son who were found dead in their home in Co Louth.
The bodies of Mark O'Connor, 54, his wife Louise, 56, and their 27-year-old son Evan were found at the family's home in Dromgowna, outside Tallanstown village, on Monday morning.
Their joint funeral mass will be held in St Patrick's Cathedral, Dundalk, on Tuesday morning.
In lieu of sending flowers, the family have requested that donations be made to The Hub Praxis Care in Drogheda and Drogheda ABACUS School, "reflecting Mark and Louise's care and generosity to others and the inspiration to many that Evan had become in his short but full life".
Mourners are also requested "to wear odd socks in honour of one of Evan's individualistic traits" in the days up to and including the funeral.
Staff at Praxis Care where Evan had attended for the past nine years, described him as "nothing short of a bright shining star".
Drogheda Abacas Special School paid tribute to Mark and Louise as "founder parents" and Evan as one of its first two pupils.
"Both Mark and Louise were passionate advocates for their son Evan and for all autistic people."
Robert O’Connor, 31, of Drumgowna, Louth Village, appeared before a special sitting of Drogheda District Court last Tuesday charged with three counts of murder.
