## The LaPointe Family’s Decades of Documentation
The paper trail that Ernie LaPointe and his family assembled over the years is not a recent project, built hastily in anticipation of a DNA study. It is the result of decades of careful preservation of documents that connect the family’s living members to the historical record of Sitting Bull’s descendants.
LaPointe has described the general shape of his lineage publicly: Sitting Bull had daughters who survived him, and through those daughters the family line continued. The transmission ran through women — through daughters and mothers — rather than through sons and fathers. This is not unusual in genealogy, and it carries particular significance in the Lakota cultural context, where kinship systems and family identity have dimensions that are not always captured by the Euro-American documentary record.
Birth certificates, death certificates, enrollment records, and family trees can trace a lineage when the documentary infrastructure was sufficient to produce those records consistently. For Lakota people living through the late nineteenth and early twentieth centuries — a period of radical disruption, relocation, forced assimilation, and systematic dismantling of Indigenous community structures — the documentary record is often incomplete, fragmented, or held in archives that are not designed for family access.
LaPointe’s family preserved what they had. When the Smithsonian’s Repatriation Office began its research process in 2002, Bill Billeck’s team spent approximately five years reviewing that documentation, cross-referencing it against historical records, and establishing to the museum’s institutional satisfaction that LaPointe and his sisters were the closest living lineal descendants of Sitting Bull in a legal sense — entitled, under the National Museum of the American Indian Act, to receive the repatriated items.
