The second and third words are 'Pastor bap.' I think the first word mostly reads 'Inf.' This is a guess: inf is used as an abbreviation of infrascriptus so it would mean 'The undersigned priest baptised...' Think you're right about 'E de G.'
I've just read that the church in Ballyorgan wasn't built until 1857. However, "according to Begley, the old parish of Darragh (now Glenroe) included Farrihy, Kildorrery and Mullahy. All three of these places are in the county of Cork" so might explain why the priest recorded the church where the baptism took place.
