Delay families in Tracton circa 1800 - siblings?

I have spent quite a few hours searching under Delay at https://churchrecords.irishgenealogy.ie/churchrecords/ and organizing the results. I am pretty certain I have the correct father and mother for my 2nd great grandfather. He had a brother who emigrated to the US with him, and the data are pretty clear. I don't think there are records that can get me back a generation further, but I thought I might try to find some siblings of my 3rd great grandfather. I have come up with some possibliltes, but I don't know how I would ever verify them. Any ideas? 

Perhaps my work will help somebody else, even if I can't make any firm conclusions.

Patrick Sr. could have been one of the two Patrick Delays in East Ferrenbrien in the Tithe Applotment book in 1833. 
Ellen Leahy was perhaps related to John Leahy in Knocknamana in the Tithe Applotment book in 1833 (just guessing because Knocknamana is next to East Ferrenbrien) 
William and Luke Delay/Dunlay emigrated to Boston, Massachusetts, then Cape Vincent, New York, USA.
