The Irish owners of Selfridges, Brown Thomas, Primark and Penneys are topping Ireland's Rich List.
Hilary Weston, her daughter Alannah and their family top the list, published in The Sunday Times, with an estimated wealth of €14bn.
It is their eighth consecutive year at the top of the newspaper's Rich List.
Businessman Denis O'Brien is in second place on the list, followed by John Dorrance and Dermot Desmond.
There are 32 new entrants to the Rich List, including actor Pierce Brosnan and golfer Rory McIlroy.
Meanwhile, the only musician on the Irish Young Rich List is Niall Horan of One Direction.
The Sunday Times says this year's list shows that "money is being created fairly evenly across the economy. Areas like information technology, medical equipment, manufacturing, specialist finance and agri-business generated most of the 32 new entrants. While construction and property are growing at 9%, they only contributed one new entrant".
