Hi,
Thank you for your message.
Have you tried looking in Church records for Andrew? If you could find his birth/baptismal cert his father's name should be listed on it.
Most Catholic records are held locally. One website which may help you is the irishtimes website where they give an overview of what records are available in specific parishes. For Gowran parish follow this link:
