I wasn’t sure how to order a birth certificate from Ireland. Today I figured it out.
I came across http://www.rootsireland.ie on twitter. I went on to the site and did a search for our grandfather. It came back with an exact match, but I had to give them my credit card to view and print the information. So, I did. It cost me 5 euros. I printed the information that was shown on the screen, but I still wanted to get a certified birth certificate.
On the rootsireland.ie site there was a link for other resources. After getting on the other resources page there was a link for http://www.groireland.ie. I clicked on that and I found a page where I could order a birth certificate. http://www.hse.ie/eng/services/list/1/bdm/Certificates/ I typed in all of the information I found from the first site and ordered a birth certificate for 20 euros + 2 euros for shipping. I am pretty excited to receive it. I hope it does not take that long.
