comparatively recently Coldridge was spelt Coleridge.
According to the historian, Risdon, who completed his
Survey of the County Of Devon about three hundred
years ago, the name is derived from the poorness of
the soil. It is thought that it was once a large wooded
area. The Readers Digest Complete Atlas of the British
Isles gives Coldridge as meaning Charcoal Ridge. If
it was once heavily wooded, they could both be right!
