Group Structure
O’NEILL AND BRENNAN LIMITED has no recorded parent company — it sits at the top of its own group structure, with 1 subsidiary recorded beneath it across 2 jurisdictions. 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 1 subsidiary spans Ireland, Germany 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.
