The person said something like - oh, you should speak to him, there, it was he that first described boulder burials. Billy ? - the copper mining guy from Ireland.
Sean O' Nuallain ? He suggested the copper connection . Same thing was applied to rock art at one time . As the boulder burials are in a pretty well defined smallish area it might be difficult to argue against coincidence but it does seem a possibility particularly when you consider there are plenty areas with copper and no boulder burials .
