Gary,

A fascinating line-up, with interesting possibilities. If you are going to
try to assign segments, I'm very interested in the process. I'm now up to
more than 50 atMatches over all of my ancestry; and am now starting to get
several atMatches from the same ancestor. Most are on different segments,
but I've got two groups which include 3 of us with the same ancestry and the
same atDNA segment. Since the 3 of us, in each case, are widely sparated
cousins and the matching segments are over 7.7cM, I think that specific
segment must come from (or perhaps through) the husband or wife of the
Common Ancestors we have.

Once you've established a long segment that's tied to one Common Ancestor,
you're saying it's IBD. Then it's fair to look at smaller segments within
the larger one.

I don't think I know enough to be called a consultant, but I'd like to be
involved.

I've been trying to figure out if it's possible to partially reconstruct
blocks of DNA from my 5th great grandfather.
I've had 13 of his descendants (see chart at:
[1]http://www.millerfamilyhistory.com/Abraham%20Descendancy%20DNA%2002.jpg)
tested with FTDNA's Family Finder. They descend from 7 different
children of one common ancestor, Abraham Miller. Most are 4th or 5th
cousins.
If this would be possible would anyone here be interested in consulting
on such a project?
Thanks!
