What changed: The family has the objects.

They have physical custody of materials that were taken from their ancestor without authority more than a century ago.

That custody is meaningful — not as a simple restoration of what was taken (nothing can restore what the century of separation cost), but as a recognition of who the objects belong to and who has authority over them.

What changed: The scientific record now includes a peer-reviewed study confirming, in the specific idiom of genetic analysis, a familial relationship that family history and documentary records had established through other means.

That documentation is available in contexts where scientific evidence carries institutional weight.
