text: http://www.openstreetmap.org/way/72903671 has name=Morriston Road but adjacent http://www.openstreetmap.org/way/39845678 has name=Moriston Road. Several other stretches of ways in the area have either spelling (http://www.openstreetmap.org/node/477704822 links two Moriston Roads and one Morriston Road...). Presumably they are not actually named differently? Should confirm thew spelling on-site and update OSM accordingly
