From an Old French name, Raimund, of Germanic origin, from ragin ‘advice, decision’ + mund ‘protector’. This was adopted by the Normans and introduced by them to Britain. Subsequently it dropped out of use, but was revived in the middle of the 19th century, together with several other given names of Old English and Norman origin.
Dutch: 1. from Middle Dutch coker ‘case’, ‘sheath’, ‘cover’, perhaps a metonymic occupational name for a maker of such articles or for a messenger or official who carried letters or documents in a case. 2. occupational name for a cook, from an agent derivative of coken ‘to cook’.
