The Dreyer Family Papers is a collection of 30 letters between 1860 and 1872. This collection of letters, from the Bancroft Library at University of California, Berkeley, is apparently associated with an immigrant named John Dreyer (1831-1906) and his wife Anna Catrina Döscher (Dreyer) (1835-1905) who was from the Cuxhaven area and migrated to California in the mid-19th century. John Dreyer was a rancher and the family wrote and received letters from their relatives in Germany as well as relatives who had also emigrated to the U.S. and exchanged information about their own state of health, financial situation or information about their daily lives.
