Various derivations have been suggested for the name of the Stannergait. Some ingenious theorist has derived it from “Stannery-gait,” similar in form to the term applied to the tin mines in Cornwall; but no tin has ever been found here. The most reasonable derivation is from “Stanner–gait,” the Stony Road, which is topographically descriptive. The name is found in charters of the sixteenth century.
