Chaffin
A surname most likely tied to the French name Caffin/Cauvin, rather than to English “chaff.”
The #3,629 most common surname in the United States (2010 Census) — about 1 in every 31,563 Americans shares it.
Etymology
The surname is traditionally treated as a variant of Caffin, and some older sources connect it with French forms such as Cauvin. That points to a French-origin family name that was reshaped in English spelling over time, especially in areas where French names were commonly adapted or Anglicized. The exact root is not fully certain, but the historical evidence favors a French surname lineage rather than a direct link to the English word “chaff.”
History
Lower explicitly cross-referenced Chaffin to Caffin, and later onomastic works note Chaffin as a form found in Normandy and in French-related name groups. The name also appears among families in English-speaking settings, including the United States and New England, where French surnames were often simplified in spelling. Because the records are inconsistent, the surname’s precise branch may vary by family.

Fun fact
A 19th-century Boston surname list filed Chaffin alongside several other French-looking names, showing how readily such spellings entered American records.
