The McCauley's were early settlers in Prescott County. They settled in "Centrefield". Other early settlers with them were Darragh, McKinley, McCrank, Beggs. They were settlers from County Antrim, Ireland.A description can be found in Cyrus Thomas "History of counties Argenteuil and prescott". here's a link. http://archive.org/stream/historyprescott00thomuoft#page/628...
There was no catholic parish until one was built in Curran. the early settlers had to go to Montebello, PQ. I have had success finding Darragh info in these parish records. they are part of the Drouin collection on Ancestry.CA.
You might find some leads on Madden in the book below:
