Code of Federal Regulations Title 43. Public Lands:  Interior § 43.10.14 Lineal descent and cultural affiliation

(a) General. This section identifies procedures for determining lineal descent and cultural affiliation between present-day individuals and Indian tribes or Native Hawaiian organizations and human remains, funerary objects, sacred objects, or objects of cultural patrimony in museum or Federal agency collections or excavated intentionally or discovered inadvertently from Federal lands. They may also be used by Indian tribes and Native Hawaiian organizations with respect to tribal lands.

(b) Criteria for determining lineal descent. A lineal descendant is an individual tracing his or her ancestry directly and without interruption by means of the traditional kinship system of the appropriate Indian tribe or Native Hawaiian organization or by the common law system of descendence to a known Native American individual whose remains, funerary objects, or sacred objects are being requested under these regulations. This standard requires that the earlier person be identified as an individual whose descendants can be traced.

(c) Criteria for determining cultural affiliation. Cultural affiliation means a relationship of shared group identity that may be reasonably traced historically or prehistorically between a present-day Indian tribe or Native Hawaiian organization and an identifiable earlier group. All of the following requirements must be met to determine cultural affiliation between a present-day Indian tribe or Native Hawaiian organization and the human remains, funerary objects, sacred objects, or objects of cultural patrimony of an earlier group:

(d) A finding of cultural affiliation should be based upon an overall evaluation of the totality of the circumstances and evidence pertaining to the connection between the claimant and the material being claimed and should not be precluded solely because of some gaps in the record.

(e) Evidence. Evidence of a kin or cultural affiliation between a present-day individual, Indian tribe, or Native Hawaiian organization and human remains, funerary objects, sacred objects, or objects of cultural patrimony must be established by using the following types of evidence:  Geographical, kinship, biological, archeological, anthropological, linguistic, folklore, oral tradition, historical, or other relevant information or expert opinion.

(f) Standard of proof. Lineal descent of a present-day individual from an earlier individual and cultural affiliation of a present-day Indian tribe or Native Hawaiian organization to human remains, funerary objects, sacred objects, or objects of cultural patrimony must be established by a preponderance of the evidence. Claimants do not have to establish cultural affiliation with scientific certainty.
