Geoffrey
wiktionary
From Middle English Geffrey, from an Old French aristocratic name, Geoffroi[dʒɔfreʲ] (> West Middle French Geoffrey, East Middle French Geoffroy), itself from Proto-French forms (latinized in -us) Jotfredus, Jozsfredus, Josfredus (10th century) and Jof[f]redus, Jofridus, Jaufredus, Geffredus (11th century), [1] and ultimately of Proto-Germanic origin. The second element is *friþuz(“peace, sanctuary”). The first element may be *gautaz(“Geat”) (making the Proto-Germanic term *Gautafriþu), as opposed to *gōdaz(“good”) or *gudą(“god”) in Godfrey; this would also make it related to Jocelyn. [2] The name was introduced to England by the Normans in the 11th century.
