Church of Ireland records begin in 1693 while the records for the corresponding Roman Catholic Parish begin in 1820. Have you exhausted the sites listed below in your search so far?
There are some places where you can search online, however these websites do not have complete collections and many do not cover the period after 1900:
www.familysearch.org has a huge database of genealogical records including some church records for Ireland.
www.rootsireland.ie have a large collection of Irish Church records, however you have to pay to use this site.
http://churchrecords.irishgenealogy.ie/churchrecords/ have begun a project to upload Irish church records to their site free of charge. However so far only Counties Dublin, Kerry, Carlow and parts of Cork have been covered.
You could have a look at the Tithe Applotment Records 1823-1837 and the Griffith?s Valuation 1847-1864. Even though these only list the head of household, it can be useful information:
