Have you tried looking at Irish Genealogy?
Try searching Irish genealogy for the parents marriage first if you don’t have that, but keep in mind the records at that time were all in Latin.
You’ll only find baptism records if there are any so try searching for Honora for Nora Hickey, Gulielmus for William and so on.
There are a number of Honora Hickey baptisms on irishgenealogy.ie. for that time period.
