Coby

Coby is an English name functioning as an informal short form of Jacob, which derives from the Hebrew Yaakov, meaning "supplanter" or "one who follows at the heel," a reference to the biblical patriarch who grasped his twin brother Esau's heel at birth. It is also used as a variant spelling of Koby or Cobie, and shares its ultimate root with the related names James and Jacques. The name gained broader use in English-speaking countries during the twentieth century as standalone given name, independent of its longer source form.
