Etymology
Jeffrey is a surname derived from the medieval given name Geoffrey, with later spelling influence from forms like Jeffery and Jeffs. The name goes back to a Germanic personal name commonly explained from elements meaning “god” and “peace,” though some older sources also connect it with related Germanic forms built on “district/territory” plus “peace.” In practice, the surname usually began as a patronymic from someone called Geoffrey/Jeffrey.
History
The surname appears in medieval records in England and later developed alongside many spelling variants, including Jeffery, Jeffs, Jeffcock, and Jeffkin. Nineteenth-century surname writers regularly treated Jeffrey as a short form or altered spelling of Geoffrey/Godfrey. It is especially familiar in Britain and the English-speaking world, where it remained in use as both a surname and a given name.
