The largest Indian tribe in the United States, the Navajo Nation consists of over 200,000 citizens and covers northeast Arizona and parts of Utah and New Mexico. Since membership criteria varies from tribe to tribe, there are no uniform membership requirements. In general, a person must possess a blood quantum of ¼ as well as be able to trace their ancestors to the Navajo tribe. While the following steps will help you to trace your ancestry, full requirements for tribal membership are kept with the Navajo Nation and may only be learned by contacting the Navajo Nation directly.
Gather vital records about your family in order to conduct a trace of your Navajo ancestry. These records include the names of ancestors, their dates of birth, marriages and deaths, the places they lived, their brothers and sisters, and their tribal affiliation. In addition, a Certificate of Indian Blood will help establish and lend credibility to a blood quantum.
Seek help from the National Archives and Records Administration. A number of other offices, like the Office of Navajo Tribal Records, are at your disposal to help locate documents and establish a line of Navajo ancestry.
Determine whether your ancestors are on an official tribal roll or census (the original list of tribal members listed in the Navajo constitution) by contacting the National Archives and Records Administration or the Tribal Enrollment branch of the Bureau of Indian Affairs.
Contact the tribe directly once you have acquired the proper documents in order to find out if they have records of your ancestors. Likewise, membership will only be given by contacting the Navajo Nation as detailed membership criteria are set forth in the Navajo tribal constitution. You can find contact information at navajo.org.
