Hundreds of people attended the funeral of Jason Corbett in Limerick this afternoon.
The 39-year-old father-of-two was found with fatal head injuries at his home in North Carolina earlier this month.
Mr Corbett's children were accompanied to the church by his sister and her husband, Tracey and David Lynch.
They are now the guardians of Jack and Sarah Corbett.
The children were allowed return to Ireland after a protracted legal battle over custody rights.
The funeral mass of Mr Corbett took place at Our Lady Queen of Peace church in Janesboro, the church where he was baptised, and just a short distance from his former family home.
Some of his favourite things were brought to the altar at the beginning of the mass; Munster and Liverpool jerseys, a golf ball and tee and a photograph of him with Jack and Sarah.
In his homily, Fr Pat O'Sullivan said that what truly matters today is that Mr Corbett was Jack and Sarah's dad and he loved them very much and did all he could to provide for them with much love and fun
He said that he was John and Rita Corbett's son and they were so proud of him and that he was a beloved brother to his siblings.
Jason Corbett was one of eight children, and has a twin brother, Wayne.
Fr O'Sullivan also spoke of the recent candlelight gathering in Limerick that had brought much hope and peace to the family at such a dark time.
He said his family and friends were foremost in his life and he received a lot of support after his first wife, Mags, died in 2006.
Her family, the Fitzpatricks, also attended the funeral. Mr Corbett will be buried with his first wife in Castlemungret Cemetery.
Meanwhile, in North Carolina, Mr Corbett's second wife, Molly Martens, who was stepmother to Jack and Sarah Corbett for eight years, is appealing the court order allowing the children to return to Ireland.
She and her father Thomas Martens, a retired FBI agent, are described as "persons of interest" by police investigating the death of her husband.
