Ollie

Ollie is an English diminutive of Oliver, which derives from the Old French Olivier, itself traced to the Latin Olivarius, meaning olive tree planter, though some scholars connect it more broadly to the Germanic name Alfher. The olive branch has long symbolized peace, lending the name a classical and noble resonance throughout medieval Europe. Oliver gained wide popularity in England partly through the legendary hero Oliver, one of Charlemagne's paladins in chansons de geste. Related forms include Oliver, Olivia, and the Scandinavian variant Olof.
