Mary Kate Byrne, also known as Poppy, was born on August 14, 1904.
The resident of Grange Maganey, Co Kildare, never smoked or drank alcohol and avoided processed foods and biscuits -- although she did enjoy a daily fry-up.
She was also an avid reader and read newspapers every day up until her death, according to her grandson, Willie Byrne.
Mrs Byrne's large extended family, including her sons Michael and Liam and grandchildren and great children, visited her regularly at her home.
She will be removed from the Killeen Church in Mageny tonight, followed by Requiem Mass at 11am tomorrow.
Pastor's niece jailed for theft
A pastor's niece and her boyfriend have been jailed on charges they burgled the clergyman's home while he conducted a Christmas Eve service.
Pittsburgh police charged 28-year-old Jessica Hirth and her boyfriend, 26-year-old Jeremiah Kelly, both of Ross Township, with burglary, receiving stolen property and criminal conspiracy.
Hirth and Kelley allegedly stole a handgun, laptop, credit cards and rare coins from the home of Rev. Michael Guthrie.
Guthrie told police he hopes his niece will seek treatment for the drug problem he believes fuelled the burglary.
