The 1st Earl of Shrewsbury was also created Earl of Waterford, in the Peerage Of Ireland , and Hereditary '''Lord High Steward of Ireland''', in 1446 , and the two earldoms have remained united ever since. 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 Viscount Mountgarret proves his presumed claim to the 1328Earldom Of Ormonde , the Earls of Shrewsbury would lose this distinction, but they derive higher Precedence from their English earldom in any event.
In 1856 the Earldoms of Shrewsbury and Waterford passed to a branch of the family who also hold the titles of Earl Talbot and ''Viscount Ingestre'', both created 1784 , and ''Baron Talbot of Hensol'', created 1733 , in the Peerage Of Great Britain .
