I have now published my preliminary analyses of the Wirral megalithic sites
at Overchurch, Arrowe Park and Fender Lane in 'A Wirral Megalithic Mystery'
(Amazon Books) if anybody is interested. I have also been scanning the Wirral 19th century OS maps and found several other standing stone groups. Overall I think there may be over 150 such stones, including part of a large double stone circle. Happy new year.
