The ex-Taoiseach’s daughter Eimear Mulhern said the immediate family were overwhelmed. The response from the public was unbelievable, she said.
“I have received so many, most wonderful letters from people that I didn’t know ever knew him or even heard of him,” she said. “And in Kinsealy it’s the same.
“These are from people who actually met him, who knew him, who he did something for, people we never knew he knew, projects he was involved in, interests he had. It’s just absolutely overwhelming.”
Mr Haughey, 80, died at his Abbeville home in north Co Dublin on June 13. He had battled against cancer for 11 years and also suffered from heart problems.
Ms Mulhern, her mother Maureen, and brothers Conor, Ciarán and Fianna Fáil TD Sean were at his bedside when he died.
“He had been very sick for a very long time but he wasn’t going to give up,” she said, speaking for the first time since Mr Haughey’s death.
“He was fighting it right up to two days before he died. He certainly lived a life to the full. In recent years it was difficult for him.”
Ms Mulhern admitted that while on a recent trip to Kerry — where her father was a frequent visitor — she felt a hand on her shoulder.
“Like everybody who has had a bereavement, when somebody very close to you dies, you do sense they are still around,” she said.
She added that even after her father’s death, his loyal friends continue to visit the family home and her mother, who recently underwent a hip replacement.
“The house is still alive but there is definitely a big gap in it,” said Ms Mulhern.
