A List of People and Characters Named Jeffrey or Jeff

Jeffrey is a common English given name, and a variant form of the name Geoffrey (itself from a Middle French variant of Godfrey, Gottfried).
It has been argued that the common derivation of Middle French Geoffrey, Jeffery from Godfrey is mistaken, and that the names reflect two separate first Germanic elements god vs. gaut, which became conflated in Old High German by the end of the early medieval period
