Louth-born animal health and veterinary products entrepreneur Eddie Haughey, who was also known by his former title Lord Ballyedmond, died in a helicopter crash in 2014.
His Norbrook Laboratories business is now owned by his wife Mary and the family, to whom €104m of assets, including properties and farmland, were transferred at the end of 2015. It was reported that the value of the estate that he left after his passing was €472m. In 2016, the company reported it had 1,800 employees and for the 12 months to last July, it made £50m profit on £272m of sales. It is now run by former Sisk boss Liam Nagle.
The family also owns castles in Northern Ireland and Cumbria in the north of England, as well as an estate in Norfolk. A house that he left in one of London's most expensive postcodes, Belgrave Square, which was bought in 2006 for €18m, is probably worth at least €60m.
It's not clear if it has been sold in the past year, but a planning application for the listed building described it as a family home and rich in architectural detail, complete with a huge dining room. Photos showed gold was the dominant colour of much of the interior decor. There was also a valuable Joshua Reynolds painting among €4m of contents of it that were auctioned off last year.
Other assets included a partially-built 27,000-sq ft house in Co Louth, where Haughey was born, and a house in Dublin's Fitzwilliam Square, which was reportedly sold, as well as two islands on Lake Victoria in Uganda. The business became one of the largest suppliers of veterinarian products in Africa.
