Caoimhín O’Neill survived the horrific crash which claimed the lives of his mum Mairéad, his grandmother Margaret McGonigle, and his mum’s friend, Racheal Battles.
All three women were killed as they returned home from a holiday in Turkey.
They will be laid to rest today after two separate requiem services in their Co Donegal home village.
Caoimhín also lost his dad in recent years. The 13-year-old, who recently made his Confirmation, took to Facebook to say a final farewell to his loving mum.
He wrote: “R.I.P Mammy Nanny and Racheal fly high god bless GBNF [gone but never forgotten].”
Dozens of people replied to Caoimhín’s post.
A cousin of Caoimhín’s, Katie Goddard, wrote: “Stay strong cuz, you’ll get through this, how’s everyone doing?xx.”
And brave Caoimhín replied: “Grand sticking with it Katie.”
On his Facebook page, Caoimhín has proudly displayed a picture of his mum, stepdad Pauric, and himself on their wedding day.
The village of Bruckless, on the outskirts of Killybegs, will come to a standstill today when the three friends are laid to rest.
The bodies of Margaret McGonigle and Mairéad Mundy have been reposing at Mrs Mundy’s residence in Ballyloughan, Bruckless.
