I generally use Brian Mitchell's RC and Civil parish maps, from his "New Genealogical Atlas of Ireland, 2nd edition" as a guide in these cases. Mitchell describes the RC maps thusly: "The maps included show the locations of Roman Catholic parishes by the middle years of the 19th century." As I recall, I believe these maps are the ones used on the Irish Times website. Superimposing the two types of parish maps for the county of interest, you'll find that a parish on the RC maps comprises one or more civil parishes within its boundaries (usually), or the reverse (occasionally). Tipperary seems to be quite consistent in this regard. I noticed only one of the latter situations - in N. Tipp., the civil parish of Toem was divided into an RC parish of Cappawhite and "most" of the RC parish of Kilcommon. The division was (and still is??) between the townlands of Curraheen and Clonmurragha. A more difficult example is across the border into Co. Limerick. The civil parish of Doon, and the RC parish of the same name have different borders on their western sides. Doon civil parish abuts Abington CP near its northern end, and Tuogh CP along the rest of the western edge. But Doon RC parish's western border seemed to follow an arbitrary curved sweeping line (not following townland borders) which reduced the size of Doon parish and gave the leftovers to Cappamore RC parish - which had then increased in size from it's civil parish incarnation as Tuogh. I suspect that a number of townlands were "divided" by this revised border. There is another way to get caught. Quite a number of civil parishes - in all counties - were divided into two or more separate entities. When the RC parishes are examined in these areas, sometimes the divided civil parishes "end up" in different RC parishes. (In Co. Carlow, Fennagh civil parish's 4 parts were divided amongst 3 RC parishes). And, most significantly, the changes in RC parish boundaries that have occurred over the decades since the mid-1800's makes things even more confusing.
