Hi, still not spoken to the D inlaw, but I found this reference.

"There are three fields behind Fearby called "Standing Stones"(1), and although there are no traces now it is possible that this may have been the site of one of these temples (comparing to Thornborough). Mr Fisher in his History of Mashamshire of 1865 talks of circles of upright stones having recently existed near to Healey." - Susan Cunliffe Lister - Days of Yore, 1978.
