John, the vast majority of these sayings are used in Ireland all the time or were used a lot. It would nice to have citations for them all, but failing that I think it's better to allow people to decide for themselves what they want to take on board. Some of the older sayings an Irish person might just about remember being used from years ago, and they might be interested in reading these phrases again. I would also take the one or two ones I haven't heard before with a grain of salt, the others are many decades or centuries old.
