A surname or place name, likely of English origin, possibly indicating a location by a cold stream or related to historical settlements.
From Old English cald (cold) + well (spring/stream). This toponymy suggests a geographical feature name that became a family surname.
Cadwell as a place name appears in the Domesday Book, meaning it was significant enough for Norman record-keepers to document in 1086—pretty cool that a word about a 'cold well' is that old.
