Hi Jan,
Thanks very much for your message. I hope that someone with information makes a connection with you.
I believe that the Crossibeg that you are referring to is Crossabeg Catholic parish in Wexford.
http://www.irishtimes.com/ancestor/browse/counties/rcmaps/wexfordrc.htm
You could try looking at the parish records for more information. Most Catholic records are held locally so you may need to write to the local parish priest for possible assistance. One website that you may find useful is the Irish Times where they give an overview of what records are available in specific parishes. It also shows you where copies of the records are available. For Crossabeg parish, follow this link:

You could also try searching online at:
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.
You could also check for record of the family in the land records pertaining to Ireland in the 19th century. There are two:
The Tithe Applotment Books (1823-1838) found at http://titheapplotmentbooks.nationalarchives.ie/search/tab/home.jsp
and Griffith?s Valuation (1848-1864) found at http://www.askaboutireland.ie/griffith-valuation/
Please note however that these records are divided according to civil parish and not Catholic parish. Here is a list of the civil parishes that fall under Crossabeg Catholic parish:
