Scottish: nickname from Gaelic cam ‘crooked, bent’ + beul ‘mouth’. As a result of folk etymology, the surname was often represented in Latin documents as de bello campo ‘of the fair field’, which led to the name sometimes being ‘translated’ into Anglo-Norman French as Beauchamp .
Irish (North Armagh): adopted for Gaelic Mac Cathmhaoil ‘son of Cathmhaol’ (literally ‘battle chief’): see Caulfield and Cowell .
English: variant of Camel , under the influence of the Scottish name (see 1 above).
