I know this reply is way out of date but I've only just seen this site.
Is it on record anywhere that Cleddon Hall was a school back in about 1945/1950?
If it is of any interest I was a pupil there at that time.
German prisonners of war were sorting the roads in the area and we pupils would spend our time off with them.
I think the owners/Head Master was a Mr. Hamilton.
