Sheila, You might also try The Irish Catholic Directory which has been published annually since the 1830s. It names and gives parishes for all clergy. I don't know where you are located but you may find a local Catholic library which could find out where there are archive copies. Or send a begging message for a lookup to a newsgroup like soc.genealogy.ireland. The name maybe RODIGAN, rather than Radigan. All good wishes, Richard Callanan London, England.
