These papers cover four generations of the Job business, and reflect its diverse interests and holdings. The business records consist mainly of balance sheets and directors' reports, and reveal the many subsidiary concerns in which the family and its parent companies had invested. The papers also contain many legal documents, including examples of nineteenth century indentures, mining leases, property conveyances, share certificates, agreements and leases. Series 11-13 deal largely with the Liverpool side of the family, Samuel Job and Robert Hugh Job in particular, and in their capacity as executors of wills. Three photographs were found with the collection, one of Indian Harbour, c.1892, and two of 'Corner Bank House, Bell Tower and Fish Store, Winter House where S.D.G. was born June 8, 1890', one of which was taken in 1928 and the other at an earlier date.
