MYSTERY ! . . . Was it ever Elenor Glyn’s house ? [Elenor Glyn was a British actress, novelist and scriptwriter. She specialised in romantic fiction, which was considered scandalous for its time!]
Butterpool, as it was originally called, was built in 1904, by Mr W Fitz-Norman Ellis, a wealthy and beneficent businessman (with connections to the arts), as a fishing and summer retreat. Fitz-Norman Ellis employed local workers to build and make alterations during slow winter months when other work was scarce.
Lledr Hall later became a Christian guest house, then 1974 was bought by Salford City Council as an outward bound centre.
If you look closely, it appears that one of the family was added later ! . . .
