A woman never fully recovered from the devastating loss of her only daughter in the Omagh bombing, her son has said.
Doreen McFarland died suddenly at her home at Woodvale Avenue in the town last Saturday at the age of 77.
Her teenage daughter Samantha was killed when the car bomb exploded in Market Street on Saturday, August 15, 1998.
The Real IRA atrocity claimed the lives of 29 people and unborn twins.
The 17-year-old had been a voluntary shop assistant in the Oxfam charity store alongside her best friend Lorraine Wilson (15), who was also killed after they were evacuated into the path of the car containing the device.
At the time Samantha, a former pupil at Omagh High School, was studying for her A-levels at Strabane College.
Her older brother Richard McFarland said the bombing had been the "defining moment" of his mother's life.
"Part of my mum never recovered from that. Samantha was the light of her life," he told the Ulster Herald.
"While she did have a rich life since the passing of my sister, it left a great space that was never filled."
Richard said his mother remained a positive and giving person right until the end of her life. "As a mother and as a grandmother we will remember her as someone who gave and never asked for anything in return.
"She never complained, and she had much to complain about."
Richard said she had faced much adversity, loss and pain, but her strong devotion to her faith never wavered.
"My mum always said: 'That's this thing called life'."
He added that after Samantha's death almost 22 years ago their mother became devoted to charity work, and in particular focused on raising money for the Wyresdale Children's Home in Nepal.
"Samantha had expressed an interest in going to Nepal and I think that's where it came from," he explained.
"Whatever money mum raised through her charity (work) went to this school. It was her entire focus."
Richard also paid tribute to his mother's generous spirit, fairness and love of people.
Doreen, a retired NHS administrator, is survived by her husband Gerald, Richard, other son Jonathan, daughters-in-law Gillian and Pam, grandsons Harry and Matthew and wider family circle.
Due to the Covid-19 restrictions the house and funeral were strictly private this week.
The cortege left Doreen's late residence on Wednesday morning for a private cremation in Cavan.
Family and friends lined the nearby Hospital, Crevenagh, Great Northern and Dromore Roads to pay their respects.
