Meaning & History
A rare Welsh surname, believed to be of Cornish origin. This surname is made up of two elements. ‘Ed’ is not a shortened form of Edward, but derives from the ancient (Old English?) ‘ead’ meaning ‘prosperity’ and/or ‘happiness’. This also gave rise to names like Edmund (‘prosperity protector’), Edward, (meaning ‘prosperity guardian’) and Edwin (‘prosperity friend’). The second element, ‘vean’ or ‘vane’ means ‘little’ or ‘the younger’. The Cornish ‘byghan’ became mutated in the same way as the Welsh ‘bychan’ became ‘fychan’ (i.e. ‘vychan’) when added to a personal name, and performed the same service of distinguishing between father and son where they had the same name. In Wales, this ultimately led to the well-known surname Vaughan. Edevane and variants, therefore, would seem to have the sense ‘the younger happy one’ or ‘the younger prosperous one’.
