i suspect these are duplicates:
Cwnwch Eithinog
http://www.themodernantiquarian.com/site/8980
should be:
Cefn Cnwchelthinog
http://www.themodernantiquarian.com/site/8463
and
Pen Rhiwiar
http://www.themodernantiquarian.com/site/8464
should be:
Cefn Gwenffrwd
http://www.themodernantiquarian.com/site/8966
there was a duplication for the CEFN GWERNFFRWD CIRCLE but it seems you have deleted that?
thanks
