I agree that the civil parish borders should go through the townland's e.g. (Ballyboleen and Magheraeagh etc.) If you look at the historic OSI 6 inch 1837 map, you can see the borders going through the townlands. http://map.geohive.ie/mapviewer.html
That map belongs to OSI so I would say that is only a guide, if you know what I mean. Do we have another open licence source with these borders?
