Crossabeg/Ballymurn Parish is situated in the south east corner of Ireland, in Co. Wexford. It is washed by the Irish sea on the east coast and it is bounded by the Slaney river on the west. It is at the end of the motorway which runs from Belfast to Wexford, making its final entrance on the Wexford side.

Historians tell us that the gospel, the story of Jesus Christ, came to this part of Ireland prior to St Patrick. It was transmitted through the traders and customs transporters, which was an interaction between Spain, France and the south east of Ireland. However, the coming of St Patrick would have integrated and enriched the first beginnings of the faith which were already present.

Faith in Jesus Christ is deeply rooted in the lives of the people of Crossabeg and Ballymurn. Names like St Ibar, St Killian, St Patrick and St Bridget are very historic and much loved. Ancient and historic schools existed and thrived in this area.

When the Franciscans arrived in Ireland in 1240, records show that Saunderscourt, Kyle and The Deeps were all places which played a big part in welcoming the Monks. Much history surrounds the suppression of the schools, churches and monasteries from 1540 to 1756.

The areas of the Parish are an amalgamation of smaller areas such as St Patrick, St Bridget, Tykillen and Kilmallock. These areas make up today the full extent of the Parish of Crossbeg/Ballymurn.
