    Lee,
    While I'm getting up to speed on the two articles you mentioned, have
    you read the following?

    American Indian mtDNA and Y Chromosome Genetic Data: A Comprehensive
    Report of their Use in Migration and Other Anthropological Studies by
    Peter N. Jones (July 31, 2004)

    http://www.iiirm.org/publications/Articles%20Reports%20Papers/Genetics%20and%20Biotechnology/Jones%20DNA.pdf

    It seems like a fairly comprehensive summary.
