Immediately above WILLIAM CONNOLLY & SONS UNLIMITED COMPANY is ROSSELLEN UNLIMITED, holding 100% as filed in WILLIAM CONNOLLY & SONS UNLIMITED COMPANY's own shareholder record with Companies Registration Office (CRO). Each of these downward relationships is derived rather than filed: resolved by matching entities across the registry network, not stated directly in a single document.
Those 2 subsidiaries span Ireland, United Kingdom jurisdictions, though this list should not be read as complete — subsidiaries only become visible here where shareholder data has actually been filed with a register, so holdings in jurisdictions without that filing simply won't appear. One of the 2 go a level deeper still, with its own further subsidiaries recorded beneath it — additional ownership layers this view doesn't expand.
