I have been in touch with someone who has Spillanes who are most likely connected to mine. We found some church records in the RC parish of Cloughjordan although the families lived in Offaly. Cloughjordan is the RC parish the covers the general area of the civil parish of Modreeny. Was your family Church of Ireland or Roman Catholic? I think it is worth our while to see if there is any connection with our families. My email address is firstname.lastname@example.org
It might be easier if we emailed.
