There seem to be quite a few pre-civil registration Irish church records in IGI so suspect that some were allowed to be copied/extracted.

I will re-phrase the latter

I did at one time do lot of looking up on the I.G.I Fitch for Scotland Ireland or England which are the same as you see on the net (exept the no source). A few times i was asked to look up a Birth or a marriage they were catholic, they had looked on the net in Ireland but they were not there.Would i please find them.I had never previously found people i had looked for that were catholic,but i looked anyway

I never found it.So i came to the conclusion at the time that the Irish that are on the I.G.I were none catholics.Even now it is hard to locate catholic records.
