So young, so wise, so loaded

Most of the members of the Rich List are old duffers. Outside of technology, it takes time to build a fortune. The billionaire 20-something Collison brothers, John and Patrick, are the richest youngsters by a mile.

Limerick biotech entrepreneur Kieran Curran (34) sold his Gencell diagnostics group to multinational Becton Dickinson last year for about €132m. The scientist owned the majority of the shares in the innovative company.

Mullingar's Niall Horan (21) is the youngest member on the Rich List and owes his wealth to his singing, dancing and goofy look as one of the members of global pop phenomenon, One Direction.

Rory McIlroy (25) is now Ireland's richest sports star following a $250m deal with Nike. Ireland's record goal-scorer Robbie Keane (34) just keeps on banging them in and his lengthy career has seen him transferred for €87m in total, earning him a big slice. Hollywood stars Michael Fassbender, and Colin Farrell may be on different career trajectories but their bank balances have plenty of zeroes… at the right end.

Outside of sports and entertainment, inheritance is the source of most of the wealth for the majority of 20- and 30-somethings on the list. Edward (35) and James (34) Haughey are now at the helm of Norbrook Laboratories following the tragic death of their father, Eddie Haughey, in a helicopter crash last year. He was Northern Ireland's richest man.

Danielle (32) and Cillian (31) Ryan are sitting on a €158m fortune inherited from the estate of their late father, Cathal, who was one of Ryanair co-founder Tony Ryan's sons. She is now creating her own super brand, Roads.

Jamie Rohan (39) has a 15pc stake in property group Rohan Holdings, which was set up by his father, Ken. It is one of the biggest industrial and commercial property owners in the state.

Donal Quinn (36) is one of supermarket tycoon Feargal Quinn's five kids. Each of them owned 11pc of Superquinn, netting €33m apiece when it was sold in 2005.

Just creeping the wrong side of 40 are a few highly successful entrepreneurs, including Kilkenny-based Terry Clune (42), who owns Taxback.com, and Brian Enright (43), who runs global logistics group, Syncreon. Eric Moseley (43) founded and almost floated the €400m online staff reward operator Globoforce, and Breon Corcoran (43) filled his pockets at Paddy Power before taking over as the highly paid boss of Betfair.

Green insulation firm Kingspan is run by Gene Murtagh Jr (43), who has seen the value of his shares rocket, while Alan Burke (43) is now a genuine 'master of the universe' at private equity group KKR, after selling his Avoca Capital for over €100m.
