Dear Ms. Duecy,
Thank you for posting your request on History Hub!
We searched the National Archives Catalog and located a series titled Applications for Enrollment in the Five Civilized Tribes, 1898 - 1914 in Records of the Bureau of Indian Affairs (Record Group 75) that includes a file unit Dawes Enrollment Jacket for Cherokee, Cherokee by Blood, Card #501, Silas Harlan. These records have been digitized and are available using the Catalog. For access to any non-digitized records, please contact the National Archives at Fort Worth (RM-FW) via email at email@example.com.
Since the Cherokee were an Eastern tribal nation and part of the early removals, the National Archives has custody of records for the tribe that date back to the 1830s when the first removal rolls were compiled. We searched the National Archives Catalog and located a series titled Eastern Cherokee Census Rolls, 1835-1884 in the Records of the Bureau of Indian Affairs (Record Group 75) that has been digitized and is available via the Catalog.
We also located a series titled Census Rolls, 1815-1869 in Record Group 75 that has not been digitized or microfilmed. For access to and/or copies of this series, please contact the National Archives at Washington - Textual Reference (RDT1) via email at firstname.lastname@example.org and also inquire about other relevant BIA series regarding the Cherokee..
If your Cherokee relatives moved west due to the removal, there are 115 additional series in Record Group 75 that you may wish to review. For access to these series, please contact the National Archives at Denver (RM-DV) via email at email@example.com.
