Are you sure you have their names spelled correctly? I checked a few sites that would surely turn up something but they didn't. If they had a brick and mortars store, definitely check with the Vermont department of revenue or taxation (whatever they call it) and request a copy of their business license. This will at least give you a lead but I do find it strange that I can't find anything on the net about them which is almost impossible these days.
