The Montana Historical Society has recently added a section on its website for the African Americans in Montana Heritage Resources Project. This is an excellent project, well worth checking out, and potentially invaluable for researchers interested in the African American West, particularly for the online access it provides to information from census records from 1870-1930. The website includes biographical information for every African American individual listed in the 1870, 1910, and 1930 federal censuses, as well as biographical information drawn from city directories, church records, newspapers, etc.
An interactive time-line contains information about African Americans in Montana from 1805 (when York, likely the first individual of African descent to enter what would become Montana, arrived with the Corps of Discovery) to 2007 (when Miles City resident Johnnie Lockett Thomas received a Montana Governor’s Humanities Award for her work on African-American experience in the West).
This is a great website, so do check it out if you have a chance.
