Ireland's OS dont have online maps of any decency that I can find, they do have a horrendously expensive CD Rom though that I'm thinking of getting (wont be much use up a mountina in gales and rain though!) so if I do splash out I can do searches for you if thats possible.

You could also start a thread here with names, I'm sure with the growing number of people on this side of the pond we could make a decent effort of tracking down most places. Would love to see more folklore for Irish places, there's a guy I know who lives for this stuff, doesnt have a website or anything but is a warehouse of legends and folklore. He may be able to help out also with identifying and maybe expanding the folklore on places in Ireland.
