Hi David, welcome to the Ireland Community! I’m more than happy to point you in the right direction. :D
Civil registration as we know it today was not introduced in Ireland until 1864, and before that the records were kept in the form of baptismal, marriage and burial records at local parish churches. All of the remaining records from this time have been collected in genealogical centres assigned to their county. You can find the contact details for the Tipperary Genealogy Centre, along with other centres, on the official National Archives website
Another great source of online information is Family Search
, where you can dive in the digital historical records to uncover more about your ancestors.
I hope this helps! :)
