In the Martyrology of Tallaght, it lists the feast dates of five principal Pre-Patrician Christian Saints as being Abbán of Moyarny, Ailbe of Emly, Ciarán of Saigir, Declán of Ardmore and Ibar of Beggerin. All are said to be originally from Munster and also as being the earliest recorded Christian Saints that had existed in Ireland prior to the arrival of Saint Patrick. Most notable of the five is Ailbe of Emly, he is the Patron Saint of Munster and also known as St Eilfyw in Wales, where he founded a tiny community called St Elvis in Wales believed to have been one of the smallest parishes to be established in Britain, which is named after him, its just four miles north of the ancient city of St Davids. Its been suggested by certain scholars that it was Saint Ailbe who baptimized Saint David 454 AD at Port Clais in Dyfed. In 2000 Terry Breverton, a lecturer at Cardiff University, while promoting his book, suggested that the rock star Elvis Presley's ancestral roots came from the Celtic prehistoric site of Preseli Hills in Pembrokeshire and may have had links to a chapel at St Elvis.
