A positive match would provide strong evidence but not absolute certainty.

Geronimo had relatives — members of his extended family, members of the same Apache lineage group — whose DNA would overlap with his in certain markers.

A match would indicate that the remains are from someone closely related to his known descendants; determining whether that person is specifically Geronimo would require additional analysis and the assessment of historical context.

A negative match — if the DNA from the remains does not match the DNA of Geronimo’s descendants — would be more definitively informative.

It would establish that the remains are not Geronimo’s, though they might still belong to another member of the Fort Sill Apache community.
