Ann's ancestor, William Walby. was an gamekeeper who was living in Hoppetts Wood, Essendon, somewhere near Camfield Place, and asked for details of his employment. I oint out that gamekeepers were licensed and suggest that there a a number of ways in which records of gamekeepers may be recorded which do not apply to the average estate worker. See Walby, Essendon, c1875-1890, gamekeeper for full details. (Beatrix Potter wrote The Tale of Peter Rabbit while staying at the Camfield Place.)
