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.
English: from the Middle English personal name Edward, Old English Ēadward, composed of the elements ēad ‘prosperity’, ‘fortune’ + w(e)ard ‘guard’. The English personal name also became popular on the Continent as a result of the fame of the two canonized kings of England, Edward the Martyr (962–79) and Edward the Confessor (1004–66). They certainly contributed largely to its great popularity in England.
