Chriss Roche died at Marymount Hospice in Cork after suffering a short illness.
She had been living with her high-profile daughter, a former Labour party presidential candidate, at St Lukes in the city for a number of years.
Born in Liscarroll in north Cork, Chriss lived most of her life in Clonmel, Co Tipperary.
Family friends described her as a “lovely woman” who “lived an active life right up to the end.”
One friend, Andrew Moore, from Cork city, said she was a “well-read, interesting woman who was a great conversationalist.”
“She was great company and she retained her keen intellect until the end. Her family will miss her greatly,” he said.
Chriss died peacefully on Saturday with her four children, Dónal, Conchubar, Len and Adi at her side.
Her husband died a number of years previous. She had moved to Cork when he came to a nursing home in the city.
Removal will take place tonight at 7.30pm from Marymount Hospice to Holy Family Church, Military Hill, Cork with requiem mass on Tuesday at 11am.
Ms Roche will be buried at St Bridget’s Cemetery in Buttevant.
