The Montague Family papers consist primarily of legal and financial documents pertaining to the administration of the estate of William Henry Kemp Montague, who passed away in 1890. His estate was managed by his wife, Hortense Caleff Montague. Some of her personal correspondence is also present in this series. In addition to Hortense's papers, a few pieces of correspondence and ephemera are included from her daughters Stella Montague Schneider and Helene Montague Collin. The papers of her middle daughter, Lilian, are in the Henry Zenas, Jr., and Lilian Montague Osborne Family Papers series. Also included in this series is the personal correspondence of Rodney Montague and his issues of the newspaper the Spiritual Telegraph Fireside Preacher. Rodney wrote his sister-in-law (and second wife) Louisa Denison Montague after his marriage to her sister in 1843. After they arrived in California in 1856, he wrote to Louisa while travelling around the state for business. Other recipients and addressees of this correspondence are Rodney's siblings, in-laws and sons.
