There really was a Thomas Cobley (the real deal, not just a namesake), and his headstone is by the main door of the village church in Spreyton, not far from Okehampton in Devon. A step away is an excellent pub called (of course) the Tom Cobley Tavern. Definitely worth a small detour off the A30 if you're down this way. At this time of year the tree-lined path to the church is a joy, with primroses and celandines abounding, and you'll get a very decent pub lunch!
