Tim No,it doesn't work that way. I think you have assumed that the 4 volumes per year contain different LOCATIONS,when in fact they contain different DATES. So vol.4 = Jan-march births (or marriage,death) vol.9 = apr-jun vol 14 =jul-sep vol 19 = oct-dec .for the areas listed below. Ireland is divided into 5 areas,ROUGHLY diagonal bands North to south across the country. There are 4 Quarterly volumes for each area - 20 volumes for the whole country each year. Galway,Mayo,bits of Clare, Sligo,Roscommon, + parts of Kilkenny,Tip,Waterford,Cork,Wex, all come into volume 4,9,14,19. If you wanted,say Dublin, you would need vol.2,7,12,17. ( Volume 4 splits at Scariff or Swinford,if I remember correctly, so Tuam and Westport are in 4-2 ,if applicable, along with ALL the eastern/southern counties mentioned above -KIK,TIP,WAT,WEX,Cork) Each volume is arranged alphabetically by the Main registration district or PLU which is in your case Clifden. It comes near the beginning after Ballina,Ballinasloe,Ballinrobe,Boyle,Castlebar,etc.but before Galway,Gort,Glennamaddy etc. I'm sure you get the picture. So the whole of the Clifden PLU is in that volume,as well as the entire county of Galway. Clifden PLU is divided into sub -districts,Renvyle, Roundstone and Lettermullen (I think it's just the 3) . Depending on which townlands you want,they will always be listed in that particular sub-district. However,I always check all of them ,in case a woman returns to her parents' home for the birth,and that might cross the sub-district boundary.In that particular event,the place of birth determines which sub-district the child is registered in,but the father's residence is always noted on the form. It's a bit complicated to explain,but it makes sense when you have seen a volume on film. Bottom line,if you want to get ALL the births for one year for one townland,you MUST get all 4 films. So 28 films EACH for B,M,D. It's a big undertaking,and you should not go into it unprepared. First of all,I have templates pre-printed (I use excel) to transcribe onto,then put on PC later. That way ensures you don't miss a piece of info. If you have family in other counties covered by the film,take those details at the same time,so you don't have to go back at a later date. But mainly,decide if it is really worth the effort. ALL the births for that period are covered by familysearch.org + Vital records 2 (in fact,probably ALL on familysearch by now). The only difficulty for you is that familysearch gives only the main (sometimes sub) registration district,not the townland. So it's a lot of effort to go to , when the information is already out there, albeit not in as much detail. Cathy
