Goff
A surname with several roots, most often linked to Welsh/Irish Gough or to a Celtic word for ‘smith.’
The #1,081 most common surname in the United States (2010 Census) — about 1 in every 9,559 Americans shares it.
Etymology
GOFF is usually treated as a variant of Gough, a Welsh nickname surname from a word meaning “red” or “ruddy,” but some older surname writers also linked it to a Celtic/Armorican word for “smith.” In Cornish material, the related element goff appears in place-names and surnames with the sense “smith,” which supports a craftsman-related explanation in some families. The spelling can also reflect later anglicization or regional pronunciation rather than a single fixed origin.
History
The name is well established in Britain and Ireland, with spellings such as Goffe and MacGough/ MacGoff appearing in older records. English and Irish surname writers often cross-reference it with Gough, while Cornish and Breton scholarship points to a smith-related word in some local names. Because these traditions overlap, different Goff families may not share the same origin.

Fun fact
