How can I confirm if a Thomas Byrne is my GG grandfather because I'm after looking at the irish genealogy website and there is nearly a hundred born in the surrounding areas.

Have you looked at the church marriage record yet? Thomas' father is listed in the civil marriage record but the church record might list the name of his mother.
After that you just do what the rest of us have to do in cases like these- search and then look at each and every record.
