THE four-year-old twins of a woman who died over the weekend had started primary school just days before their mother's tragic death.
Siobhan Kennefick-Aherne (23) from Cootehill, Co Cavan, died on the way home from a music festival on Saturday night.
Ms Kennefick-Aherne was the mother of three children -- four-year-old twins, a boy and a girl, and a six-year-old daughter.
The twins had just started school in the junior infants' class at St Michael's Junior National School in Cootehill.
Ms Kennefick-Aherne took ill on her way home from the Planet Love Festival in Co Antrim, where her boyfriend Noel was a security guard.
The festival was in its 13th year and ran from 2pm until 1am. About 10,000 people attended the event.
Ms Kennefick-Aherne left the festival at around 9pm after her boyfriend's security shift ended. She was travelling home in a car with her boyfriend and another couple when she took ill.
The group called an ambulance from a service station at Moneymore in Derry.
The Northern Ireland Ambulance Service said Ms Kennefick-Aherne was taken to Antrim Area Hospital where she was later pronounced dead.
Planet Love Promoter Eddie Wray extended his deepest sympathy to Ms Kennefick-Aherne's family and to her boyfriend.
He said that Ms Kennefick-Aherne did not take ill, and did not receive any medical treatment, while at the festival.
Northern Ireland Police said a post-mortem examination had been carried out, but the cause of death was undetermined.
They said further tests would be carried out.
The directors and staff at Clubsec Management Ltd, the security company at the festival, released a statement offering their sympathies to Noel and the Kennefick family.
The funeral Mass will take place today at 1pm followed by burial in Cootehill.
