The second of the funerals following last week's crash in Co Tipperary will take place today.
The funeral of 24-year-old Luke McSweeney and his 18-year-old sister Grace, will take place in Clonmel this morning.
Large crowds are expected to attend the siblings funeral mass in Clonmel this morning.
The brother and sister died in a collision along with 18-year-olds Nicole Murphy and Zoey Coffey while on their way to a Leaving Cert results celebration last Friday evening.
The cortege will make its way from Mountain Road to the quays and into the town centre, with mass taking place at 11.30 am at St Peter and Paul's Church on Gladstone Street.
Chief celebrant will be Fr Billy Meehan, parish priest of St Mary's in Clonmel, who baptised Grace and Luke and also officiated at the wedding of their parents, Paul and Bridget.
Nicole Murphy was buried yesterday in Kilcash, while the funeral of Zoey Coffey takes place on Saturday.
