Chafin
A surname most likely derived from a nickname or from a regional spelling of a French name, especially associated with Appalachian and southern U.S. usage.
The #8,981 most common surname in the United States (2010 Census) — about 1 in every 84,750 Americans shares it.
Etymology
Chafin is a surname of uncertain but likely nickname-based or surname-adapted origin. In English-speaking areas it is often treated as a variant spelling of Chaffin, which has been linked to Middle English words for coarse chaff or, in some cases, to French surname forms that were reshaped in Britain and America. The name may therefore have begun as a descriptive byname for someone associated with grain processing, roughness, or a similar trait, though a direct single-source derivation is not certain.
History
The surname is best known in the United States, especially in the South and Appalachian regions, where variant spellings often stabilized differently from one family to another. Like many less common surnames, Chafin likely reflects spelling variation rather than a single fixed origin, and it is closely related in form to Chaffin and other similar names. Modern bearers are mostly found in the U.S., where the name appears to have remained comparatively localized.
