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: 1. variant of Blade, from the plural or genitive singular form. 2. habitational name from a place of uncertain location and origin. Its status as a habitational name is deduced from early forms cited by Reaney, such as Alan de Bladis (Leicestershire 1230), Hugh de Bladis (Staffordshire 1258), and William de Blades (Yorkshire 1301).
