Footnote.com continues to add a wealth of historical- and genealogical-relevant material. A new addition will interest many people who are researching American Indian ancestry: Indian Census Rolls, 1885-1940.
According to the Footnote.com web site, most of the records include the English and/or Indian name of the person, roll number, age or date of birth, sex, and relationship to head of family. Beginning in 1930, the rolls also show the degree of Indian blood, marital status, ward status, place of residence, and sometimes other information.
Only persons who maintained a formal affiliation with a tribe under Federal supervision are listed on these census rolls. There is not a census for every reservation or group of Indians for every year.
This title, NARA publication M595, consists of census rolls submitted annually by agents or superintendents of Indian reservations as required by an 1884 Act of Congress. There is not a census for every reservation or group of Indians for every year. Some tribes, particularly those in the East, were never under Federal jurisdiction and therefore not included in this publication.
