Opening your DNA results to find 0% Indigenous Americas—despite family stories of a Cherokee great-grandmother—is one of the most common surprises in genetic genealogy. Conversely, finding unexpected Indigenous ancestry can be equally confusing if you have no known Native American ancestors.
This guide explains how Ancestry identifies Indigenous DNA, why it often “washes out” over generations, and why a DNA test cannot get you tribal citizenship.
How AncestryDNA Reports Indigenous Americas Ancestry
Ancestry does not label DNA with specific tribal names like “Cherokee,” “Navajo,” or “Sioux.” Genetic markers are tied to regions, not political tribes.
If you have Native American ancestors, your Ethnicity Estimate will likely show one of the following broad regions:
- Indigenous Americas—North: (Canada & United States)
- Indigenous Americas—Mexico: (Includes parts of the SW United States)
- Indigenous Americas—Central
- Indigenous Americas—South or Andean
Important: You generally cannot search your DNA matches for tribal names (e.g., “Seminole”). You can only search family trees for those keywords.
Why Native American Ancestry May Not Show Up in DNA Results
If your family lore insists you have a Native American ancestor but your test says 0%, it is usually due to Genetic Recombination.
You inherit 50% of your DNA from each parent, but you do not get 50% of their ethnicity. You get a random shuffle. If your father was 10% Indigenous, he might have passed that entire 10% to your brother, but only 1% (or 0%) to you.
The “Wash Out” Statistics
The further back the ancestor, the less likely you are to inherit any of their DNA. Here are the concrete numbers:
- 3rd Great-Grandparent: On average, you inherit only 3.125% of their DNA.
- 5th Great-Grandparent: You inherit less than 1%.
- 7 Generations Back: At this level, there is a greater than 50% probability that you possess zero DNA from that specific ancestor, even though you are biologically descended from them.
If your “full-blooded” Native ancestor was born in the early 1800s (approx. 6–7 generations ago), it is statistically normal for their DNA marker to have completely washed out of your specific genome.
DNA Testing vs Tribal Citizenship
A common misconception is that a DNA test can prove you belong to a tribe.
- DNA Tests: Prove biological/ethnic origins (e.g., “You have ancestors from the Americas”).
- Tribal Citizenship: Proves legal/political status.
Most sovereign tribes (like the Cherokee Nation) do not accept DNA tests for citizenship. Instead, they require you to provide vital records (birth/death certificates) proving you are a lineal descendant of someone listed on specific historical rolls (like the Dawes Rolls).
How to Find Indigenous Ancestry That Did Not Appear in Your Results
If you believe the DNA is there but just didn’t show up in your test, you can try these strategies to find it.
Strategy A: Test an Older Relative
Because DNA dilutes with every generation, your parents or grandparents hold more of the original DNA than you do.
- Example: If your grandmother has 12% Indigenous DNA, she might have passed only 6% to your parent, and your parent might have passed 0% to you. Testing her directly may reveal the ethnicity that was lost in your file.
Strategy B: Test a Sibling
Since siblings inherit a different 50% from parents, your brother or sister might have inherited the Indigenous segment that you missed.
- Statistically: If a parent has a small amount of Indigenous DNA (e.g., 2%), there is a roughly 18% chance that one sibling will inherit it and the other will not.
Why Some People See Unexpected Indigenous Americas DNA
Sometimes, users are surprised to see small amounts (1–2%) of Indigenous DNA when they expected none.
- Latin American Roots: Many people with Hispanic ancestry have significant Indigenous DNA (often 20–50% or more) due to the history of colonization in Mexico and Central America.
- Colonial History: In the early colonial US/Canada, intermarriage occurred more often than recorded history suggests. A 1% result often points to a single ancestor from the 1700s or 1800s.
Conclusion
While DNA is powerful, it is not a perfect record of every ancestor who ever lived. If your Indigenous heritage is from more than 5 generations ago, the lack of DNA evidence does not disprove your genealogy—it simply means the genetic signature has faded with time. To confirm these distant connections, you must rely on paper trails and traditional genealogy rather than ethnicity estimates.
