Lappallagh townland (Islandeady parish, Westport union) around 1870. I see the problem. I can give you my best guess. I spend a lot of time with the revision books, though not for this particular area. It's the electoral division which is critical. You can obtain this by using the valoff.ie website, though of course, there may have been changes in voting districts since the 1930s. Let me know if you are not familiar with this site and I can tell you how to navigate it. Cornanool is in Castlebar electoral district, and is at the END of the first book. The revisions were simple at the start, taking up less paper, so the whole district would be on that one film. Later Revisions, cancellations and re-numbering took up more paper, so part of the district would be on the 2nd film, and therefore I suggest that the remainder of the district, including the townlands right at the end, will be on the 3rd film # 857693. Townlands in Islandeady parish fall into either Clogher or Islandeady electoral divisions. Lapallagh is in Islandeady ED, but it is not listed as such in the LDS catalogue. I think this may simply be a cataloguing error, so I would order # 857733. But you could email the Valoff to check the correct ED in 1870. It might be helful if you could ask them to name the townlands on either side of Lapallagh in the Revision book. That should certainly narrow it down. Or you could ask them to photocopy the relevant pages for you. There is a charge, but it's so much easier to make sense of it in COLOUR! Regards cathy
