Iffa and Offa East

Baronies were created after the Norman invasion of Ireland as divisions of counties and were used the administration of justice and the raising of revenue.

The title Earl of Carrick was first created in 1315 for Sir Edmund Butler, Justiciar of Ireland, by King Edward II of England.

The title is linked to the manor of "Karryk Mac Gryffin" (see history section of Carrick-on-Suir for elaboration).

Edmund was granted a charter of the castle and manor of Carrick, Macgryffin and Roscrea to hold to him and his heirs sub nomine et honore comitis de Karryk on 1 September 1315.

However, the neighbouring barony of Kilnamanagh was split into Upper and Lower half-baronies, being allocated to the north and south ridings respectively.

The river forms the border with neighbouring County Waterford for much of its journey through the barony, with the exception of a "box" around Carrick-on-Suir which straddles both banks.
