Cantwell
A surname most commonly explained as coming from a place name, likely Canwell in Staffordshire or another local name of similar form.
The #5,259 most common surname in the United States (2010 Census) — about 1 in every 46,533 Americans shares it.
Etymology
The strongest traditional explanation links Cantwell to an English place name, especially Canwell in Staffordshire, meaning someone who came from that locality. Some older writers also suggest a connection with a place ending in -well or with a related local name, but the exact starting point is not fully certain. Irish materials also record Cantwell as an established surname form, reflecting later adoption and settlement in Ireland.
History
The name is documented in English records and later turns up in the United States as well. In Ireland, Cantwell became established as a surname in its own right, and nineteenth-century Irish surname studies list it among names in use there. Because the form is relatively uncommon, older etymologists sometimes offered competing place-name explanations rather than a single settled derivation.

Fun fact
Old surname dictionaries sometimes grouped Cantwell with other names beginning with Cant- or Can-, which shows how uncertain local-name origins could be before modern place-name scholarship.
