Lord Shrewsbury is the senior earl on the Roll in the Peerage of England (the more senior earldom of Arundel being held by the Duke of Norfolk). The earldom of Waterford is sometimes called the "Premier Earldom of Ireland "on the Roll"", as the oldest Irish earldom, that of Kildare, has been a subsidiary title of the Duke of Leinster for centuries and the Earl held the oldest Irish earldom held by anyone ranked as an Earl. If the Viscount Mountgarret proves his presumed claim to the 1328 earldom of Ormonde, the Earls of Shrewsbury would lose this distinction, but they derive higher precedence from their English earldom in any event. Despite holding three differently named earldoms Lord Shrewsbury is always styled simply "The Earl of Shrewsbury".
