Thanks for the reply. What is the RCB library in Dublin? I'm not familiar with that abbreviation.
Religion has not been passed down in the family. However, I have heard from a third party that they were Protestant. This third party won't provide me sources though - just statements - and I'm trying to find the sources to verify the statements at this point.
I have tried ancestry.com as well as familysearch.org to find the records and have come up with nothing so far.
