On Tuesday, a High Court judge ruled his family should receive £163,048 from the Ministry of Defence for damages and loss of earnings.
Speaking to the BBC, his son Billy said their family was put under enormous strain following the events of Bloody Sunday.
"[My mother] had a lot of pressure on her with my dad being in hospital and trying to look after nine kids, worrying about how she was going to cope. There was just shock at not knowing what the future held," he said.
Billy said the shooting changed his father, who began binge drinking to cope with the trauma of his shooting.
"He kept everything to himself. He wouldn't confide in the family. He couldn't go back to work, he wasn't fit for the work what he was doing," he said.
"When he was out working and earning a wage he kept us fed and watered. It's hard for a man who has been doing that since he was 14 to all of a sudden not be able to work."
In 2010 the Saville Inquiry into the shootings established the innocence of all those killed and wounded.
Those findings led to the British Prime Minister at the time, David Cameron, issuing a public apology for the soldiers' actions.
He described the Bloody Sunday killings as "unjustified and unjustifiable".
Billy said he was glad his father was "vindicated", but it was a shame he did not live to see it.
"He forgave [the soldier who shot him] when he was interviewed from his hospital bed. He wouldn't hold a grudge. What's done was done. You can't change what's been done - that was his attitude," he said.
"He went to his grave with that hanging over his head. Some people get justice, some people have to wait a long time - some people don't see it and pass on.
"Money will not bring him back - it won't do anything for him. It's just money, that's it. It doesn't mean anything."
