Marcus Michael Curry

I know my Great Grandfather Marcus Michael Curry (we have also been told that he reversed his names when he became a Protestant so it might have been Michael Marcus) was born in or around Blacklion in 1841. His parents I am told died during his childhood, and he was raised by Jesuit priests and eventually became one (he later left the preisthood and came to North America where he became a Methodist Minister). I am wondering if there are records that were kept by the Jesuits, or about orphaned children that might help me get more information on my family.
