Cumberworth, in the Calceworth Wapentake of Lincolnshire, probably comes from the Old English male personal name Cumbra and the Old English element worth ‘enclosure’.
It has also been suggested that the first element is an Old English ethnonym Cumbre ‘the Cymry, the Welsh, the Cumbrian Britons’. However, the exact implications of such a name are not yet fully understood and are the subject of ongoing work by Dr Jayne Carroll of the Institute for Name-Studies, University of Nottingham.
