Dear Jane That was a very comprehensive article! The LDS is a little simpler!. Using the LDS catalogue,under Place search you enter the CIVIL PARISH . This brings up a short list,usually includes CHURCH RECORDS, 1901 CENSUS,1911 CENSUS. Click on either census,takes you to the same page! Click FILM NOTES. The 1911 census is broken down by DED + number e.g. Kilkelly 107/30-37,Kilmovee 108/1-21 ,Urlaur 109/1-11 followed by a list of the townlands contained therein,in numerical order. The 1901 ONLY gives Kilkelly 107/ 30-37 etc. but doesn't name the townlands. But you can work out the one you need by referring to the 1911. So far,have never had any difficulty finding the right film. Cathy
