Maura Horgan, 57, had taught Irish at St Enda’s secondary school and was a native of Glin, Co Limerick.
She was hit by a falling branch after a passing lorry struck an overhanging part of a street-side tree at O’Connell Avenue.
The accident happened at about 11am on Thursday but she died later, at about 9.30pm, in the Mid-Western Regional Hospital.
Gardaí are carrying out an investigation into the circumstances of the incident. A spokesman said it appeared to be a freak accident.
She had married psychologist Michael Horgan last October and had recently taken retirement, having taught since 1974.
A special prayer service took place in St Enda’s yesterday for Ms Horgan.
School principal, Gina O’Connor, said: “Maura was very well liked by everybody.”
She said the entire school was shocked at the tragic death.
Another colleague at St Enda’s said: “Maura was so happy since getting married and was on top of the world. She was a fantastic Irish teacher. The whole school is devastated. She was the loveliest, loveliest person.”
Gardaí at Roxboro Road Station would like to speak to anybody who was in the O’Connell Avenue area near the Mount Convent at around 11am on Thursday. They can be contacted on 061-214340.
The removal will take place at 8pm on Sunday to St Joseph’s Church on O’Connell Avenue, from Griffin’s Funeral Home.
The funeral will take place on Monday, afternoon Mass, to Mungret (Old) Cemetery.
Meanwhile the funeral took place in Limerick yesterday of William Carroll, a 67-year-old single man who died in a house fire at his home in St Mary’s Park at about 7.30pm on Tuesday.
Members of the Garda Emergency Response Unit, who were in the area, managed to rescue his brother Thady from the building.
