Would you be able to share more information? I can tell you that if the Pillon family were shoemakers, they may be listed in trade directories in Ireland. These are avialble on several website including:
Shane Wilson's website at this link: https://www.swilson.info/dirdb.php
Shane's site is free.
FindMyPast also has trade directories.
I am going to forward this query to a local volunteer who may be able to add further information.
All the best,
