EDIT: I just asked my wife and in her area it was "Oche na nll", or "Apple night" and nothing else was associated with it.
Plain old Halloween where I grew up (Dublin), we were never big on the "cupla focal" in the Pale.
(of course it was pushed as "All saints eve/day" by the parish. We were just glad of the bank holiday)
We always trick or treated and always had a bonfire with fireworks (illegally bought on Henry Street). No pumpkins (or turnips) though, that was a later affectation.
