PJ Mahoney from Ardrahan, who was in his late 70s, died at the scene when his car was in collision with another vehicle a short distance from his home at Kiltartan in south Co Galway.
A man in his 30s was injured in the accident and is being treated at University Hospital Galway where his injuries are believed to be non-life threatening.
Mr Mahoney’s wife Marie was laid to rest just over a month ago after she passed away following an illness.
The death of Mr Mahoney, a farmer from Tulira in Ardrahan, has caused widespread shock throughout the area as the family were well known for their involvement in sport and community projects.
Mr Mahoney was the goalkeeper on the Ardrahan team which won the Galway senior hurling championship in 1974, ’75 and ’78.
His father Junior Mahoney was the goalkeeper on the Galway senior team which captured the county’s first All-Ireland title back in 1923.
The chairman of Galway GAA, Pat Kearney, who is from Kilbeacanty in south Co Galway, said that the death of the popular farmer and sportsman had caused widespread shock.
“It’s a terrible tragedy for the Mahoney family, the second time in a month that they have had to deal with a death in the family and our thoughts and prayers are with them at this difficult time,” Mr Kearney said.
“PJ and his family are steeped in the GAA and gave wonderful service not just to the organisation but to farming and many different activities in the community. It’s unreal and people are stunned by what’s happened.”
Gardaí at Loughrea have appealed for witnesses or drivers who may have dashcam footage which might assist their investigations.
The N18 between Adrahan and Gort was closed in both directions following the accident which happened at Kiltartan shortly after 3.30pm when two cars collided. Both drivers were the sole occupants of their vehicles.
“The road is currently closed and will be closed overnight,” said a statement from An Garda Siochana. “The services of Forensic Collision Investigators have been requested. Local diversions are in place.
“Gardaí are appealing for any witnesses to this collision to contact them. Any road users who may have camera footage and were travelling in the area at the time are asked to make this footage available to Gardaí.”
Mr Mahoney died in the accident and another man was injured. He was trapped in his vehicle before he was eventually freed and rushed to University Hospital Galway where he is being treated for his injuries.
Driving conditions in the area were poor at the time as Storm Barra battered the west coast, with strong winds and heavy rain when the accident happened.
Mr Mahoney is survived by his daughters Catriona, Olivia, Lorraine and Mairead, and sons Noel and Patrick, and ten grandchildren.
Meanwhile, a man has died after he was struck by a car in Co Tipperary last night.
The pedestrian, aged in his 40s, was pronounced dead at the scene.
Shortly after 10pm, gardaí responded to reports of a road traffic collision involving a car and pedestrian on the R499 between Toomevara and Ballinamona Cross.
His body has since been removed to University Hospital Limerick where a post-mortem will take place at a later date. The driver of the car, a man in his 20s, was taken to University Hospital Limerick as a precaution.
The road is currently closed to allow for an examination to be carried out by Forensic Collision Investigators. Local diversions are in place.
Gardaí are appealing for any witnesses to come forward. They are particularly appealing to any road users who were travelling on this road at the time with camera footage to make this available to them.
