Archaeological survey of the barony of Ikerrin by Geraldine Stout - i think i browsed this one day in Thurles library and it has a rough plan of the stones.
Ill try and have a look next time Im passing through Thurles.
Great...I was browsing through a copy of this in Roscrea castle last week...I nearly bought it...now the castle is closed to April...shot myself in the foot on that one.
