Hi Richard,
I've just picked up your enquiry about your uncle, John G Clixby whilst looking at the history of Whiteley Wood Hall, Common Lane, Ecclesall, Sheffield.
John and Freda were great friends of our neighbours, Bryan and Ray Jones, on Marsh House Road, Ecclesall. Bryan Jones' family were Leyland Paint and Varnishing Company. My family often met John and Freda with the Jones. I was a student at the time in the late 1950's and the Clixbys allowed me to earn a bit of pocket money by gardening at their house at Hollow Meadows, Moscar, way up on the moors. They seemed to have a passion for large old (sometimes derelict) halls and had made an offer in October 1957 for Whiteley Wood Hall, which wasn't accepted. They went to live even further out in the wilds at Sugworth Hall, overlooking Strines reservoir. They eventually lived in Baslow Hall, which as you say is now Fischers Baslow Hall House Hotel. I think they inspired the Jones to buy and live in "The Tower" at Hathersage for a short time.
