What information are you looking for? Do you have the marriage cert of James and Mary Rielly as this will give James' father's name and will help in looking for birth/baptismal records for him.
If you don't have the cert you can download an application form at www.groireland.ie
and order the cert. A possible reference is Mitchelstown registration district 1868 volume 19 page 377. Mitchelstown registration district includes Galbally.
Hope this is of some help.
