Hundreds of people are expected to pay their final respects to Lorna Carty at the Church of the Assumption, Robinstown in County Meath today.
Ms Carty, along with Athlone couple Martina and Larry Hayes, were killed in a mass shooting on a beach in Tunisia last week - just hours before she was due to fly home.
Lorna was a nurse and volunteered with her local GAA club as a first aid officer - she's survived by her husband Declan, son Simon and daughter Hazel, her parents and extended family.
Friends have described Ms Carty as a true lady.
