Gemma Smith Maughan (76) and husband Michael own 46pc of Gowan Group, which distributes everything from Peugeot cars to LG appliances, as well as owning Senator Windows. Last October, it announced it would close two of its most prominent south Dublin car dealerships, including its landmark outlet in Ballsbridge. The group said the sites were no longer suitable for the car business and it was reported that the properties were being sold for an estimated €18m. Latest accounts show turnover rising from €167m to €182m in 2017, with pre-tax profits of €1.4m. The group was established by Maughan's late husband Con Smith in 1969. He tragically died just three years later in the Staines air crash in London. Daughters Alba, Christiana, Mary Louise and Fiona each own 13pc.
