In 1462, a charter granted to the Irish borough of Youghal in County Cork made it "one of the Petylymmes [i.e. petty limbs] of the Cinque Ports in Ireland" with all associated liberties and franchises.[1] [2] [3] [4] William Gordon Perrin assumed in 1922 that this referred to the English Cinque Ports, because in 1462 the Lordship of Ireland was subordinate to the Kingdom of England.[2] On the other hand, George Bernard O'Connor stated in 1906 that the Queen's Cinque Ports of Ireland in the reign of Elizabeth I were the important seaports on the east coast of Ireland.[5]
The medieval seal of the corporation of Youghal displayed a single-masted ship (cog), reflecting its importance as a port; while Helen Elrington suggests the seal specifically alludes to the town's Cinque-Port connection,[6] Samuel Hayman dates the seal to Thomas de Clare in the 1270s.[7]
