CRADDOCK is from the Old Welsh personal name Caradog or Caradoc which means amiable. A bearer of this name is recorded in the Latin form Caratacus and remembered for his leadership of a revolt against the Roman occupation of Wales in 51 AD. The Cradocks of England and Wales claim to be descended from this Caradoc. The family spread through several counties in England, and even in Brittany, where, at a village called Caradoc, their crest has been discovered.
Variants of the name include Cradock, Cradocke, Cradduck, Cradok, Craddoe, Caradoc.
