Gilly found this in Malcolm Bull's Calderdale Companion:
Sharp, Jack
[17??-17??] A nephew of the John Walker of Walterclough Hall.
He was adopted by the Walkers, and the family business and the Hall passed to him when his uncle retired. On his uncle's death in 1771, the son – John – ordered him to leave Walterclough. Sharp left, but took most of the contents with him, and destroyed what he had to leave behind.
In 1778, he built Law Hill House.
It is said that the family feud may have influenced Emily Brontë when she was writing Wuthering Heights.
