One of a cluster of roads named after contemporary and archaic English and Scottish counties. The others are Westmoreland Avenue, Sutherland Avenue, Cumberland Avenue, Cornwall Avenue, Buckingham Avenue, Cambridge Avenue, Dorset Avenue, Gloucester Avenue, Somerset Avenue, Kent Avenue and, bizarrely, Yorkland Avenue.
This article was corrected thanks to new information. It previously read: Named after the heath north of the humber, which comes from the Celtic for good river in Erith which has now disappeared. The district’s nickname of Spike island is after the old parish workhouse which stood in Sussex Road from about 1805. It was first written down as Northumbre in 1292 and the area as Northberland Hethe in 1529.
