Thanks - Inishfale isn't a townland on the GIS layer I have (maybe an error
with that layer?). I wasn't doubting Beggerin was a townland! Just looking
for it: I found it on my GIS layer. I can't see the orig OS maps here
http://maps.openstreetmap.ie/oocmaps.html for the Beggerin Island area. Are
they available?
