Lady Ballyedmond and her family remain the richest family in Northern Ireland according to the 2018 Sunday Times Irish Rich List, with a combined wealth of around £1.628bn.
The Northern Ireland Rich List rankings include those who were born, are resident or who have significant business interests based in the country.
A former solicitor educated at Newry High School, Lady Ballyedmond, 70, inherited the £1bn Norbrook Laboratories business, after her husband Eddie, who took the title Lord Ballyedmond, died in a helicopter accident in 2014.
She is a director of Norbook Laboratories alongside sons Edward, 38, a former barrister, and James, 37, a doctor and visiting lecturer at Ulster University. Their sister, Caroline, 42, is a criminal barrister in London and was appointed a QC in December.
With a combined fortune of £390m, husband and wife Mark Burnett and Roma Downey are in second place on the Northern Ireland Rich List once again.
