The Irishman killed in the US last week is to be buried with the mother of their children in Limerick.
Jason Corbett (39) was killed at his home in North Carolina during a domestic incident. His family are locked in a custody battle with authorities in the US who have put his children Jack (10) and Sarah (8) into the care of his second wife Molly Martens Corbett, the chief suspect in the case.
Mr Corbett remarried after his first wife, Mags Corbett, died in 2006 after suffering an asthma attack.
His sister Tracey Lynch said it was her brother's wish to be laid to rest alongside the mother of his two children in Limerick.
"It is what he would have always wanted," said Ms Lynch. "It is painful and we are trying to keep focused on what Jason's wishes were while trying to process our grief and support each other," she added.
The family has not yet had any contact with the children since arriving in the US a week ago.
However, they said they remain determined to come home to Ireland as a family.
Mr Corbett's body is to be returned home with the help of the Kevin Bell Repatriation Trust.
"It is some comfort that we are receiving so much support from home because it is difficult to carry on here," said Ms Lynch.
Colin Bell set up the repatriation trust with his wife Eithne after their son was killed in the United States in 2013.
"Our son Kevin was killed in a hit-and-run in New York two years ago on my sixtieth birthday," said Mr Bell.
"We got massive support from the people of Newry who raised money to bring him home," he added.
"We had a sum of money and we chose to use it to help bring Irish people home. Since Kevin's death we have taken 82 Irish people home."
