This is the second fire tragedy to hit the immediate family of Annemarie O'Brien.
Annemarie - who died in the Clondalkin fire along with her daughter and cousin's two children - suffered heartache in 2011.
Her brother Andrew O'Brien died in a container fire in Bray.
Mr O'Brien, who was 20 at the time, died in a blaze in the grounds of Bray's Christ Church.
His remains were found in a prefab to the rear of the church on the morning of Tuesday, January 25, 2011.
At the time of his death, Annemarie wrote a message of tribute to him on Facebook.
"Love you Andy," she wrote.
"Sleep tight bro. Thinking of you always. Miss u more than anyone could imagine. RIP."
Originally from the Fassaroe area, Mr O'Brien had been sleeping away from home for a number of nights. He had been at a number of locations, including the place where he lost his life.
His remains were found after firemen had been called to attend to the burning outhouse at around 4am.
By 5am that morning, they had discovered his body.
It was impossible initially to tell whether the victim of the blaze was male or female.
DNA analysis later confirmed that the deceased was Mr O'Brien.
The shed on the church grounds was often used as a shelter for people with nowhere else to go.
