Apart from Terve and the current name Tarvin, the village has also been referred to as Tervyn (e.g. in records of an assault on a monk in 1326) and Terfyn in the accounts of a trip from Chester to London in 1811, in which is it again suggested that Terfyn comes from the British word for boundary, though in this case it is suggested this might refer to the boundary of Delamere Forest.
