DNA Research #DNA Re: What tests if any are available? #dna
I would disagree with the answer given to your question. The surest
way to know which wife a descendant came >from is the use of mtDNA
which traces the female line. I used it for this exact purpose to
prove my great grandmother was the daughter of my 2nd great
grandmother (Elwine) and not another wife or family as a cousin
insisted. Turns out his ancestor was born to Elwine out of wedlock so
he may not be a Wiedebusch!
This will not distinguish between sisters however. If two of the wives
were sisters they will carry the same mtDNA. To do an mtDNA test you
will need to find a direct line female ancestor, i.e., mother to
daughter to daughter and so on. A male can be tested if he is the son
of the direct female descendant. He can not pass the mtDNA on so only
the son who is the immediate descendant will carry that mtDNA.
FF will only trace 4-5 generations back in general. And because of the
way recombination (the admixture you receive) works you may or may
not find enough DNA in an FF test to confirm a match. Because the FF
test crosses both genders you can not identify what DNA came from
whom. So a match could be >from either the shared father, i.e.,could be
from Borukh or >from some other family member you may share. It canrequire far more tests, I have a (cousin?) that recently did the test
with a known cousin, and they did not match. Their shared ancestor is
a 3rd great grandparent on one side and a second great on the other.
However, they do match other people that both match. In my own line
many of my "second" cousins do not match my two siblings and vice
versa. Again, this is due to the admixture and the way the
recombination of DNA is passed down through our ancestors - one may
completely drop out in only a few generations or fall below the
testing companies threshold of matching - usually 7 cM. Which is like
what happened with my cousin and her paper documented cousin. The
fact that we belong to endogamous populations make our use of FF even
FF is useful and should not be dismissed - most people like it because
of the ethnic origins that it gives - which are the least accurate
part of the tests. You may want to try it with your 82 year old and
yourself as that would not be that many generations. However, how many
generations back is your common ancestor? A Y-DNA test would be most
conclusive. Let your known male descendants know that the DNA testing
done for genetics which looks at 23 chromosomes(22 plus the X) of the
entire genome is looking for likenesses - not what law enforcement is
looking for.. They are looking at what sets an individual apart from
others for more info on this read Judy Russell's blog,

You should also check out Roberta Estes blog,

passed down and other DNA questions.
For example, here is a recent one:

I was not surprised that I did not match my "cousin"? as we would be
too many generations back - or may just be related through marriages.
That will require far more research which we are working on but have
not gotten to the Polish records yet and that will be what we need as
any shared ancestor we may have between the 3-4 families would
likely be in the early to mid 1800s or earlier.
