Jemmy

Jemmy is an English pet form of James, which itself derives from the Late Latin Jacobus, rooted in the Hebrew name Yaakov, traditionally interpreted as meaning heel-grasper or supplanter. It was used as a familiar diminutive in Britain from the early modern period, functioning much as Jimmy does in later and broader usage. The name appears in Scottish and English folk tradition as a colloquial masculine given name, and it was occasionally borne by historical figures in informal address. Related forms include Jamie, Jim, Jimmy, and Hamish.
