Rob

Rob is a short form of Robert, a name of Old French and Norman origin, itself derived from the Old High German elements hrod, meaning fame, and beraht, meaning bright. It was introduced to England by the Normans and became one of the most common medieval English names, producing a wealth of diminutives and pet forms. Rob was particularly associated with the legendary outlaw Robin Hood, whose name is a further diminutive of the same root. Related forms include Robert, Robin, Bob, and Robbie.
