Curl
Likely a nickname surname from a word for curly hair, though some historical sources also treat it as a form related to Old English ceorl (“free peasant”).
The #6,379 most common surname in the United States (2010 Census) — about 1 in every 57,872 Americans shares it.
Etymology
This surname is usually explained as a nickname connected with curly hair or a curly-haired person, since Middle English and related forms used words like curl/curly for that feature. Some 19th-century surname books also link it to Old English ceorl, the ancestor of modern "churl," meaning a free man or peasant, though that explanation is less certain for this exact spelling. In short, the name may have begun either as a descriptive nickname or as a status-based byname that later settled into a hereditary surname.
History
The name appears in English records in several spellings, and the historical evidence is mixed: some writers connect Curl with place-name forms, while others treat it as a shortened or variant form of related surnames such as Curly or Curling. It also shows up alongside continental parallels in Germanic languages, which may have encouraged later scholarly comparisons. Because the sources disagree, the safest reading is that Curl has more than one possible origin in different families.
