Doing mtDNA studies could quickly determine whether any connection existed between these bones and current tribes.

Currently the oldest such connection within California is 5,300 years (ancient skeleton to living lineal descendant).

There is an even older connection (10,300 years) between a southern Alaskan skeleton and living descendants stretching from southern California to the tip of South America.

Both of these seem to be associated with one or more early coastal migrations.
