Hi Katie
All you need to do is continue your research at IrishGenealogy.ie and RootsIreland.ie websites.
Civil marriage registers which can be viewed at
http://www.irishgenealogy.ie confirm that Patrick Curran married Mary Tobin in Paulstown RC, County Kilkenny in 1882. It records that Patrick, age 21, was son of Thomas Curran and that Mary Tobin, age 21, was daughter of Michael Curran.
Hence you are looking for births of Patrick Curran c. 1861 o a father Thomas Curran and of Mary Tobin c.1861 to a father Michael Tobin.
Prior to 1864 and introduction of civil registration of births you will have to rely on church baptismal registers to identify birth details of children and names of their parents. RootsIreland.ie holds the largest collection of church register transcripts, and with its powerful index you can conduct searches by entering name of children together with name of father. You can also further narrow your research by county, parish and range of years.
Hence a search of this website,
http://www.rootsireland.ie, reveals that RootsIreland holds baptismal record of a Patrick Curran to a father Thomas Curran in County Kilkenny in 1861 and of a Mary Tobin to a father Michael Curran also in County Kilkenny in 1861. These would appear to be the nearest matches to the ancestors you seek.
