Geoffrey is an English given name, derived from the Germanic elements 'ge' meaning 'to yield' and 'frið' signifying 'peace'. It was introduced into England through the Norman conquest in 1066 and was notably borne by several members of the Plantagenet dynasty, including Geoffrey I, Duke of Brittany (1158-1213). The name's popularity peaked during the Victorian era and has since seen resurgence in recent decades. Its most common diminutive form is 'Geoff', while other variants include 'Jeffrey' and 'Jefferson'. The name day for Geoffrey is celebrated on June 17th, commemorating Saint Geoffrey of Amiens.
"Geoffrey experienced varying popularity over the years, with a noticeable peak between 1982 and 1983 when it was among the top three names for newborn boys."
