Robby

Robby is an English diminutive of Robert, a name of Old High German origin composed of the elements hrod, meaning fame, and beraht, meaning bright. Robert was introduced to Britain by the Normans and became widely popular throughout medieval Europe, borne by three kings of Scotland as well as countless nobles and clerics. The pet form Robby, like the variant Robbie, developed as an affectionate short form and has occasionally been used as an independent given name. Related forms include Rob, Robin, and Roberto.
