The bulk of this series consists of bills paid to San Francisco service providers and merchants on behalf of Wilcox, and after his death in August 1883, on behalf of his widow, and of his divorced daughter, Mrs. Mary W. Longstreet, most probably by John Bermingham, who served as Wilcox's executor in San Francisco. The stationery and forms vividly illustrate the state of graphic design in 1880's San Francisco. The series also contains a series of letters from Bermingham to Wilcox concerning the activities of the steamer Newbern, as well as correspondence between the banker, entrepeneur, and property developer Edward Falles Spence (1832-1892)--Wilcox's agent, and after his death, Los Angeles executor--and Wilcox (to 1883) and Bermingham (from 1883). The legal papers consist almost exclusively of documents collected or created in the course of the probate of Wilcox's will, and include executor accounts, certificates of title, copies of mortgages, lists of accounts receivable and payable, receipts and demands for payments, and powers of attorney.
