Hi, ubhig,
Yes, that site was extremely limited!

I figured it was worth sending your way just in case any of those few names were your ancestors.
As you are looking at graves in that area, if you by any chance come across a grave for a Mrs. Walsh who died between 1827 and 1839 (my great great great grandmother), I would appreciate it immensely if you would be willing and able to write down the info for me. (I wish I knew her first name, but I don't.) Her husband's name was John Walsh, but his grave would not be with hers because he died later in the U.S.
I understand you will probably be too busy to look for anything other than your own--- this is "just in case." I will do my best to return the favor when I eventually get there, if you need something watched for. Enjoy your time in the Emerald Isle, and I hope your search is fruitful!
