Mayo property investor Kenny (80) and his family own large blocks of Dublin's south city business district, centred on Harcourt Street and Hatch Street.
There was a company restructuring last year which valued the business at €204m. Following the restructuring, Kenny and his wife, Margaret, own just under 11pc of Clancourt Holdings. The remaining 89pc is split equally among the five children, whose stakes are valued at more than €36m each. There are other assets.
