Content DescriptionReturn to Top

The collection consists primarily of correspondence. The earliest letters (1850-1851, 1858-1864) are nearly all written by Amalia Nichols to her sister Ann Kilbourne. The letters of 1865 and 1866 include many from Morton Post to his wife, Amalia Nichols Post, as well as those from Amalia to Ann while Amalia was living in Denver, Colorado. The majority of the letters of 1867 and 1868 are from Morton to Amalia or from Amalia to Morton. Amalia’s letters from Cheyenne dominate 1870 to 1872, but from 1873 to 1875 most of the letters are from Annie Kilbourne to her mother, Ann Kilbourne, describing Annie’s life in Cheyenne with her aunt. From 1876 to 1879 letters from Adrian Parshall are included describing his attempts to become established in Deadwood and his frustration with his long engagement to Annie Kilbourne; while Annie Kilbourne Parshall’s letters from Deadwood to her mother dominate 1880 to 1883. Three letters from Celestia Parker in Port Huron, Michigan, are also included, one of them describing Port Huron’s reaction to the death of Abraham Lincoln in 1865.

A large number of letters and telegrams of 1885 and 1886 express support for Morton Post’s appointment as governor of Wyoming Territory. The collection also includes a small number of newspaper clippings (1881-1890).
