Ms Whyte, a vet originally from Co Clare, and her two children, were killed in a suspected triple murder and attempted suicide at their Drummeer Road house in Maguiresbridge, Co Fermanagh on Wednesday morning.

The remembrance Mass was held at 7pm on Sunday night, at the Church of the Immaculate Conception in Barefield, Co Clare – Ms Whyte’s home village.
A murder investigation has been launched, while an adult male – Ian Rutledge (42), father of the two children and husband to Vanessa – remains in a serious condition at the Royal Victoria Hospital in Belfast, having also suffered severe gunshot wounds.
Police have said a suspected triple homicide-attempted suicide is one line of enquiry.
At the prayer service, the priest told the congregation that “Vanessa was a woman who gave and who gave and who gave”, and that James and Sara had “dreams that will never be fulfilled”.
He described their murders as “an unspeakable tragedy” and something that has been difficult for the parish to get their minds around.
During his eulogy, he said that Vanessa will be remembered by the parish for “her strength, and her incredible and powerful love for her children”.
“She gave it her all, to the very end,” the cleric added.
“We remember James and Sara, not just as victims of violence, but as children who played and laughed.
“They had their favourite stories, of course, favourite foods I’m sure, as well, and great dreams – dreams that will never be fulfilled, but dreams that mattered, because they were theirs.

“Vanessa was a mother. She was a daughter, a sister, an auntie, and a great friend, to so many people.
“She was a woman who loved her children fiercely. She wanted the best for them. She worked hard and she laughed a lot.
“And she carried burdens that we may never, ever fully understand. Her life was incredibly precious.
“James and Sara, young lives just beginning, so full of promise, so loved, so full of light. They’ve been taken away from this world all too soon in a violent way.
“We just find it impossible, my dear friends, to make sense of any of it. We cannot rationalise what should never have taken place.
“What we can do is remember the pain that we feel now. That pain is born out of love.

“If we didn’t love Vanessa – and so many of you would have known her – and if we didn’t love her children, we wouldn’t be grieving. This is the price that we pay for love, but it is also love itself that will help Vanessa’s family and all of us indeed to carry it over the weeks and months to come.
“Mary – and I know you’re at home and you’re listening – she was Vanessa’s beloved mother, and her grief is a very deep ocean indeed.
“No mother should ever have to endure this, and yet Mary I know will find herself surrounded by people who care deeply.”
He noted that while Vanessa’s mother Mary and her many siblings were not physically present in the chapel, they were watching the online live stream at home.
He repeatedly told them: “You are not alone.”
The Mass took place on Sunday evening to allow for Ms Whyte’s brother, Ivor, to travel home from Australia.
The clergyman also thanked representatives of St Mary’s Maguiresbridge Gaelic Football Club and Lisbellaw Hurling Club for making the journey down to Co Clare from Fermanagh for the Mass.
Vanessa, James and Sara have all been described as “active and beloved” members of both clubs.

Three candles were lit at the altar in remembrance of the murdered mum and her children, while a fourth was lit for Vanessa’s mother Mary, and the rest of her extended family.
Parish priest Father Tom Fitzpatrick said “the purpose of the service is to gather as a community and be with the family and let them know we are thinking of them and we are here in shock and in pain”.
“When something happens in a rural community, even to one person, it affects everybody. We are coming here with hearts broken. A lot of the community knew Vanessa and she was so well loved,” he commented.
A book of condolences has also been opened at the church.
Earlier on Sunday, a minute’s silence was held for Vanessa, Sara and James, just moments before throw-in at the All Ireland senior football final between the Donegal and Kerry men’s teams.
