Hi George, So far I haven't found a link with your Greatorex. Mine originally came from the Newcastle area. They only moved to Derbyshire in the 1940's to work on the railway. My Grandfather lived in Buxton and I've been told that he was a bit of a rogue so there may be other branches of the Greatorex tree still undiscovered. I'll let you know if I find a link. Good luck with your search.
