text: In other words, there are two issues here.
  
  Firstly,  the townland of "Curry (Macmanaus)" needs to be split in two, so that the northern half can be added to the Barony of "Clanmorris" and the southern half to the Barony of "Kilmaine".
  
  
  Secondly, the civil parish (CP), "mayo" (called "Mayo (clanmorris portion)" in OSM ) overlaps the barony of "kilmaine". This overlapped area is a separate CP called "Mayo (kilmaine portion)" in OSM. 
  As I see it, these should be merged into one CP called "Mayo". Because it is ok for CP to overlap baronies?
  The mayo CP then is mostly in the Barony of Clanmorris with a part in the Barony of Kilmaine.
