These records are all available through the Roots Ireland database which is a subscription site but you may find it useful with your research.
You mentioned that Michael Keane married in Piltown and that was probably the home parish of his bride. If his residence was Carrick-on-Suir, that was not very far from Kilsheelan parish.
You should also be able to access records through the Irish Genealogy website which has all the civil records indexed and many of the images online. They can be searched at the following link:

If you need any further information, please let me know.
Kind regards,
Jane.
