Twin sons Rocco and Jay were born on 20 April 2007. The civil ceremony was followed by a church blessing on 9 August at the Roman Catholic Church of St Pierre et St Paul in Gallardon, Eure-et-Loir, France and a reception at the nearby 16th-century Château d'Esclimont. On 29 April 2013, Byrne announced on his Twitter page that he and his wife Georgina were expecting their third child, and on Irish television it was announced that the baby was due around Halloween. Daughter Gia was born on 23 October 2013. Godparents for the children are Byrne's sister Gillian Byrne and her husband Mark Gallagher and Georgina's sister Cecelia Ahern and Byrne's brother Adam McGarry Byrne. Byrne Sr. sang part-time on Dublin's cabaret and karaoke scene and was presented with a Harley-Davidson motorbike by his son on his sixtieth birthday party the year before his death. In 2010, Byrne and his family organised the 'Nikki Byrne Twilight Ball', a fundraising event, in memory of their father who died in November 2009. The event raised over €200,000 and completely funded a television and radio heart attack awareness campaign in connection with 'The Irish Heart Foundation'. Byrne, and his wife Georgina, are keen supporters of the Irish Premature Babies charity. Byrne also supports UNICEF and has taken part in several UNICEF Campaigns, such as the UNICEF 'Euro for Zero' campaign where the goal was to raise as much money as possible in November 2010 for Child Survival Programmes.
