Danielle Meagher Collins was getting ready for bed when her dad called from the family home in Dublin to drop a bombshell. 'He said, "Don't make a big deal out of this, but I met your mother when she was four months pregnant".'
In shock, Danielle, then 43, asked the obvious question: 'So who is my dad?' Her father's tone was perfunctory, she recalls: 'He said, "You'll have to talk to your mum about that".'
With that, the conversation was over and Danielle was left to cry until dawn. 'I spent the whole night grieving the different life I could have had, the dad who didn't know about me.'
She had never felt close to her parents and her father had made it clear he was uncomfortable discussing the subject further. Even after her mother, Eileen, finally admitted, four days later, that she'd spent the weekend with a man called Todd in 1974, Danielle did not feel she could remonstrate with them.
To avoid her being registered as illegitimate in the strictly Catholic country, her parents explained, Dominic had been named as Danielle's father on her birth certificate.
Six years on, it's a revelation Danielle, now 49, is still grappling with.
'My entire existence has been based on a lie,' she says through tears. 'It's debilitating. Without the truth, you are nothing.
'I don't want to throw my parents under the bus but I have to be truthful. I feel betrayed. They lied to me. That was traumatic.'
The trauma was compounded by the fact that little over a year after Danielle tracked down her biological father, Todd, who had bowled her over with his kindness, he died of heart failure. 'I felt robbed of the life I could have had,' she says.
A former Harley Street dentist and aesthetic clinician, who appeared on reality television series Dublin Wives and Celebrity Big Brother, and later went on to become a successful stand-up comedian in America, Danielle is chatty and outspoken - the opposite, she says, of her strait-laced, upper-class family.
Her great-uncle was the revolutionary Michael Collins, and her parents are lawyers. Danielle, who has two younger brothers, now 46 and 31, was privately educated at Mount Anville school in Dublin, whose alumnae include former president Mary Robinson. Her summers were spent at the family holiday home in West Cork.
'I was blessed with a good education,' says Danielle, but 'I always felt something was missing.' She bore no physical resemblance to her parents, but more concerning to her was the difference in temperament.
'The family are all lawyers and politicians. I wanted to do ballet.' Her parents paid for dance classes, 'but I was the only kid there with no tutu and ballet shoes', she says. 'There was no support. There was no one in the family going to be a playwright or an actor.'
When, as a teenager, her feelings of being 'different' from the rest of the family led her to ask if she was adopted, her parents 'shut down' the question, dismissing it as 'silly nonsense'.
But she 'didn't feel Irish' and dreamed of running away to California, where she wanted to be a television presenter. Initially, however, she pursued academia, in part to make her parents proud.
A degree in aerospace engineering was followed by a degree in dentistry and a Masters in aesthetic medicine. In 2007 she set up a Harley Street clinic offering tooth whitening and Botox, splitting her time between London and Dublin.
She became something of a celebrity pioneer of Botox and in 2011 appeared in Dublin Wives - a TV3 reality series modelled on America's NBC hit The Real Housewives.
Witty and charismatic on screen, she was invited to appear on Celebrity Big Brother in 2013. Her parents were 'horrified'. 'I was made to feel embarrassed, belittled, bullied out of doing television. Dad said, "You had your shot - you were useless".'
Yet Danielle longed to return to the entertainment world. In 2016 she sold her clinic and booked a flight to Los Angeles, where she spent three weeks and felt a sense of peace. 'I've never felt like I belonged anywhere. This was different,' she says.
Over the next two years she spent more time in the city before moving there permanently in 2018 to fulfil a secretly long-held dream of becoming a stand-up comedian.
When, later that year, she confided in her dad's cousin that she felt her parents were keeping a secret from her, he told her about a letter he'd received from them in 1978.
Though it revealed Eileen was pregnant with Danielle's brother, there was no mention of Danielle, then three. In fact, her uncle admitted, he had not known she even existed. Feeling ever more suspicious, the following year she sent a barrage of text messages to her parents pretending she'd done a DNA test. 'I said somebody had better tell me the truth.'
Todd had been a set designer on films, which paved the way for an instant creative connection with his long-lost child. He and Alida, an art curator, were 'delighted' to discover he had a daughter, says Danielle: 'They took to me like a duck to water.'
Three weeks after near daily emails, Danielle flew to San Francisco to meet him. She told her parents back in Dublin in the taxi to the airport: 'Mum wanted nothing to do with it. Dad said to call him when I got back.' Of meeting Todd, she recalls: 'We hugged. He said, "You are so brave to fly here." It was the weirdest day of my life.'
Todd had congenital heart failure - a health problem Danielle says highlights her right to know her medical history - his age and ill health making their physical similarities less obvious. Yet in pictures from his youth, his blond hair was familiar, says Danielle, the baby-blue eyes the same.
While Todd was her father, he was also 'a complete stranger,' she stresses: 'It's confusing. I didn't know how to process it.'
They discovered a mutual love for the sitcom Father Ted and when they ordered a takeaway and Danielle requested a bowl to eat it from both Todd and Alida burst into laughter, because Todd always insisted on that, too.
Todd, who was born in California, had moved to Ireland with his family aged 12. He had stayed there until he was 18 and later spent summers in West Cork. 'So all my summers we were just an hour away,' says Danielle, who stayed in touch with Todd over the coming months.
Todd asked her to visit again, but she stalled a second trip. 'I felt conflicted - that I was cheating on my Irish dad.' It's something she now regrets.
One evening, in July 2019, Todd wrote to her that one of them should write about their reunion. The following morning his brother Michael texted to say Todd had died in his sleep, aged just 61.
She has yet to meet Todd's extended family, who have professed a desire to see her, because she admits that being lied to for so long means, 'I don't trust anyone.'
She has barely spoken to her parents for two years and no longer receives birthday cards. Christmas goes unacknowledged.
'It's sad and painful,' she says. Yet she is unwilling to swallow their secret any longer. 'Every day I look in the mirror and say, "My name is Danielle Collins" to show myself that I am proud of who I am. I am proud to be illegitimate. The truth will set me free.'
