Hello Nancy,
That truly sounds like a dream come true and a trip of a lifetime! Do you already know how much time you're going to spend on the island later this year?
For anyone born before 1864 the records were kept as church and parish records. While unfortunately some of these records have been lost, you can try and start your search
here. Another page you might want to look at is the
Beyond 2022 research project. By the end of June '22 this website is due to launch the
Virtual Record Treasury of Ireland online. This will be an open-access resource and a great tool for your research.
With regards to travelling from Dublin to county Tipperary there are many different ways of
getting around the island and it all depends on your personal preference. Rental cars or bus services are probably the most common options. If you have some spare on your trip, make sure you don't miss out on the
Rock of Cashel.
Please let us know how you get on with your research and if you are able to find any direct descendants.
Sarah
