I have not been giving you all the benefit of my great wisdom and insight
<grin> very often because usually someone else eventually says whatever I
would have said. This was prompted by the "What happened 50,000 years?"
thread, but it seems to me to deserve a more descriptive thread.

From the Graves/Greaves/Grieve/etc. DNA study and from others as they get
larger, I expect that we will be getting much better estimates of real life
mutations for at least some of the markers. We have a few well-documented
genealogies that go back about 20 generations. As we connect families that
are presently unconnected, I expect that we will have even more generations
to work with. I am trying to get the FTDNA 21-marker analysis for as many
branches of these large Graves/Greaves families as possible, and anticipate
that there may be more mutation than some of the discussions have so far
indicated. I certainly hope so, because otherwise we may have some serious
problems with a couple of our major genealogies. Does anyone already have
this sort of study (comparing documented lines with DNA results and
mutations rates) already completed, well underway, or in progress?

When I get more results, I plan to post family trees showing mutations by
color-coding on our Graves Family Association website. We presently have
about 75 samples back of the 100 sent to participants, and by the end of
this year I anticipate we may have a total of about 200 (depending on what
the needs seem to be after the present group of samples are all analyzed).
