For the first name Oliver, the origin is not definitively clear. There are three possible origins for the name. Oliver possibly comes from Scandinavian and is derived from Olaf. This would give the meaning “descendant of the great-grandson”. A descent from the Old High German name “Alfhari” is also probable, which means something like “warrior of the nature beings”. Another origin could be the Latin “Olivarius”, which translated means “olive tree planter”.
