Unsure how to properly tag the addresses here. The street itself is Lillebonne Way but the houses that front on to it are known as Normandy Row. Indeed, the cross street at the western end and link street to Proctor Road are signed as just being Normandy Row. The formal address looks like 49 Normandy Row, Lillebonne Way, WELLINGTON, Somerset, TA21 8FD. I have perused OSMWiki and applied the tag combination that looks "proper" for when developers do this mad two-names thing but a consensus to be absolutely correct would be nice.
