Olivier

Olivier is the French and Dutch form of Oliver, derived from the Old French Olivier, which was likely influenced by the Latin olivarius, meaning olive tree cultivator, though some scholars suggest a Germanic origin from elements meaning elf and army. The name gained wide medieval fame through the Chanson de Roland, in which Olivier is one of Charlemagne's twelve paladins and the loyal companion of Roland, making it a prominent name in the Carolingian literary tradition. The English form Oliver and the Spanish and Italian Oliviero are among its closest cognates.
