Hi Kate,
Thank you for your message.
It may be difficult to find birth/marriage records for the couple when you don?t know the parish of origin. Civil registration did not begin in Ireland until 1864 so prior to this records were kept by the local parish church and most of these still remain at local level today.
You could try searching for records online at the following websites. However please note that these websites do not have complete collections:
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 may be able to use the possible fathers in Griffith?s Valuation to narrow down parish of origin. You could look into the church records in those parishes to see if you can find any pertaining to Charles and Mary. 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 Catholic parishes in County Mayo, follow this link:

It may also be an idea to contact the North Mayo Family Research Centre, however a fee may apply. Here is their email: normayo@iol.ie
