I think I’ve hit the proverbial goldmine.
This site has several very important rolls, including one as far back as 1836 showing the amount of admixture. Here’s the link to the primary site.
If you take a look at the Ottawa/Chippewa Halfbreed Census, you’ll see that it gives the people’s names, where they live, their family and the amount of admixture. What we wouldn’t give for something like this from the 1600s or 1700s in Virginia, North Carolina and South Carolina.
Another resource is the Durant Roll from 1870 and 1908, again, with full information.
Patricia Hemp, the compiler and page author tells us that the four rolls of this microfilm publication, M2039, have reproduced the 1908 census roll (known at the “Durant Roll” for its compiler, Horace B. Durant) of the Chippewa and Ottawa tribes of Michigan, with Durant’s field notes, and related correspondence. The Durant Roll contains the names of all members or descendants of members enrolled with the Ottawa and Chippewa tribes of Michigan in 1870 who were living on March 4, 1907. The roll also serves as an index to Durant’s field notes. The field notes provided genealogical information used to determine if an individual was eligible to be listed on the census. The correspondence consists of letters received and sent by the Commissioner of Indian Affairs and Horace B. Durant which concern the enrollment process, procedures, and policy. These records are part of the Special Agent Files, 1807-1948, in the Records of the Bureau of Indian Affairs, Record Group (RG) 75, and are housed at the National Archives Building in Washington, DC.
Also included are Indian Land Allotments resulting from the Dawes Act of 1887 that allowed tribal lands to be split up and divided into individual allotments for tribal members.
