Hello Grace, the paper mill may have been owned or run by a Mr Evans who also had something to do with the corn mill.
I have a copy of a letter from an ancestor of mine (Thomas Wright) to his sweetheart (Mary Anne Giles Sadgrove) where he mentions being asked to work for Mr Evans. He states that he will work at the paper mill but doesn't want to work at the corn mill. The letter was sent from Whychbold paper mill and was written in 1824;
hope this is of some interest to you,
