Ann, I just tried to jump on this band wagon with you. Filled out the order at Ancestry by DNA and clicked submit, but that took me to a blank e-mail form. Have you (or any of you here) had that experience? I wrote to this outfit on that e-mail and sent it, but I don't believe that I transferred any of my order information with that.

Virginia, I have the same problem you do. Mom was told that she was "part Indian" by her grandfather (paternal). We have not found, let alone proven that by traditional means. Good luck in your quest!

Kay

That's correct for tests using mitochondrial DNA (female line) or the Y
chromosome (male line). None of the people you listed could provide a sample
for mtDNA or Y testing. But -- did your great-grandmother have any daughters
who had daughters? Or did her sisters have daughters who had daughters? If
so, one of them could supply the sample for a mitochondrial DNA test.

There is also a very new company which uses a number of different markers on
other chromosomes to estimate the percentage of your ancestry which came from
different "BioGeographical" origins, including Native American.

If your great-grandmother herself had 100% Native American ancestry and
married a man with 100% European ancestry, then 50% of her son's markers
would show NA patterns. If each new generation marries someone of European
background, that would dilute the number of NA markers roughly by half, so
your uncle would have about 25% of the markers and you would have about
12.5%. Thus if you choose that company, your uncle would be the best person
to test.

A few of us have ordered a test from this new company, but we won't have the
results back for some time. We'll certainly report on how well the theory
translates into practice.
