Wikipedia has a location called 'Grange Corner' pointing to here, which I think originates in the NI census. Any local knowledge of whether this place exists and if so how it relates to Taylorstown hamlet?

I find it very hard to believe that the suburb of Rathfarnham extends down even further south than here. Shouldn't it stop around Rathfarnham golf course? osm.org/relation/2643835/#map=13/53.2781/-6.2385

Missing 'Wild Nephin' wilderness area which starts around here and extends southwards for a number of KM, 11,000 hectares total:

Any local knowledge of whether Ballykelly Airport node at 1042032811 should be tagged as 'disused:aerordrome' instead of 'aerodrome'?

Wikipedia article gives 'Arle' area as being further south at osm.org/?mlat=51.9&mlon=-2.11&zoom=12#map=15/51.9000/-2.1100

Any idea which location is correct? Or if the one at this point or further east is 'Arle Court' (which is a nearby park and ride /way/35039221 and bus stop /node/1774667964 )

Is this all part of Saltash town or is there another named suburb of Plymouth/Saltash here? If there is no suburb, it might be good to add a way/relation to show roughly the extent of the town given that the center node for the town is (correctly) so far to the East.

Is this wood really called 'Isle of Man'??

According to http://www.brunel.ac.uk/news-and-events/news/news-items/press/ne_24891
this campus was 'sold' in 2007. Is it still attached to Brunel University London?
