Miss Chapman, who never married and lived through two world wars, was born on June 9, 1906 in Twickenham, London.
She nursed both her parents through old age. Her nephew, Clive Chapman, said she spent her life helping others.
“She was a true Edwardian, she had this never ending sense of duty to her family which was typical of someone from her era,” he said.
“She never lost that and she was an incredibly caring person.”
Miss Chapman spent her final years at The Telford Centre care home, Fort Augustus and had lived in the Highlands for the past 40 years.
She first came to the region after moving to Fort William from London and falling in love with the area.
Her family have paid tribute to her stoic nature after she passed away on December 18.
Although Miss Chapman was blind in her later years she remained fiercely independent and celebrated her birthday earlier this year with cake and a cup of tea.
“She was very stubborn and had a great deal of pride and dignity, she did not like to be helped,” said Mr Chapman.
“Even though she was blind she always knew when you sat next to her, she was very tactile with people.
“Gardening and animals were big loves of hers, she always liked to be involved in everything.
“We always liked to get up and see her, age really didn’t bother Irene.
“She never complained and we will remember her for her strong faith and brilliant sense of humour.”
