Civil parishes and baronies are independent of each other - one is not a subdivision of the other. > Furthermore, townlands don't > necessarily add up to electoral divisions.

After 1898, the civil parish boundary was not shown when two adjacent "parts" were in the same electoral division. In the second example, you have a single townland which is spilit between an urban and rural electoral division (again, before 1898 both the urban and rural portions would have formed a single poor law electoral division. (As an aside, the mid-20th century editions of the 6 and 25-inch maps by OSNI in Northern Ireland didn't show townland boundaries at all within urban districts.) The original practice of the Ordnance Survey, FWIW, was to treat any townland "divided" between two civil parishes or two baronies as being two separate townlands. The population returns for the 1901 and 1911 censuses - after the 1898 Local Government Act - continue to list the two "parts" of a townland separately even where both lie within the same single electoral division. > Regarding some of your specific issues: > 3: I've come across several areas with CPs covering 2 non adjoining areas > so this doesn't look that unusual e.g.: > http://www.openstreetmap.org/relation/4280429 > 4: I think it's just awkwardly shaped.
