I tried to diagram the situation in a text message, but I really needed to do
it in a graphic format, so I uploaded a file to the RootsWeb Companion at DNA
Heritage. It remains to be seen whether new papers will use Roostalu's
nomenclature, which was just formally published early this year. There is a lot of
literature that refers to H2b.

Most people in the world will have five "mutations" at 750G, 1438G, 4769G,
8860G, and 15326G, including most people in haplogroup H. I put "mutations" in
quotes, because the actual mutations occurred between the clan mother of
haplogroup H and the CRS, which is just a tiny twig branching off of H. The CRS has
the rare values and others have the ancestral values, but everything is
reported in terms of *differences* from the CRS. The closer you are to the CRS, the
fewer differences you will see on your report. I haven't seen anyone yet who
actually matches the CRS completely.
