Neice Mary Elizabeth Sutcliffe also at this address
I have him as being a son of James Leaver and Martha Sutcliffe.
Martha was born in Worsthorne in 1806 and was the (eldest?) daughter of Moses Sutcliffe and Betty Sutcliffe.
Martha's brother, Simeon, also married a Leaver...a Jane Leaver who was the daughter of a James and Betty Leaver. I think Joseph mentioned in Bannisters will is the (youngest?) son of this Simeon and Jane. This is them in 1891 and 1901
In 1891 Joseph's occupation is shown as 'Cotton Weaving(manager)'.

Interestingly, Joseph also married a Leaver...Linda Mary Leaver who was the daughter of a Thomas Leaver and Sarah Sutcliffe. Sarah is connected to my Sutcliffes though I don't know if there is any connection between her and the Martha Sutcliffe who was mother to Bannister!
Joseph and Linda are buried at Hill Lane, their gravestone is on the site
