Hi, there were a lot of dreadfully inaccurate, inadequate and out of date mapping in Fleetwood. The roundabout you mentioned had all its circular component ways named Denham Way Roundabout which I believe should be left with no name (unless I'm wrong). I have no idea whether that roundabout has a name; my feeling was that it had just been named arbitarily after one of the side roads.

Thanks for the suggested guidance, I'll check that out.
