Thank you, my friend.
The best "bang for the buck" at the moment is at Family Tree's test service: $149 will get 37 standardized markers, all but two of which are covered by the standard 43 markers that Ancestry DNA and our DNA Heritage selections covered. And that's enough to have to track for the moment, despite Family Tree's new panels that extend the total potential number to 111 markers.
With more test subjects later on, perhaps an expansion to 67 might show some branch markers. But so far, of the three groups we have do have test results for we do not appear to have much luck in finding significant branch markers in enev the largest of the three groups.
One issue is that currently Family Tree does not appear to offer the very low-end-and-upgrade-later tests any more. And DNA Heritage or Ancestry DNA did not store a copy of the initial DNA sample for potential upgrades. Family Tree does, but then we have the following issue: if the party initially tested at Family Tree but is now deceased or otherwise un-contactable, who is able to authorize and pay for an upgrade? Could the duly authorized project administrator do so? I don't know the answer to that question yet. We just have to gamble that some of these people who provided samples early on in the study have already tested to the 67 marker level or are contactable when we want or need to extend their test results to that level.
