Despite the name, Cambridge Heath probably has nothing to do with Cambridge.
It is named after a former heath, first recorded in 1275 as Camprichthesheth and also written Camprichesheth. The first part may come from an Anglo-Saxon personal name, or from an Old English plant name such as comfrey. Cambridge Heath was a small, mostly farming village in the parish of Bethnal Green until houses began to spread here in the mid-18th century.
