LCH,
My older brother always said I was the Flower of the Family, but by
that he meant "The Boomin' Idiot" not the Bloomin' Scientist. I have
always liked science, but I actually studied Primary Education.
(That's why my letters sound as though I'm writing to second graders.)
I'm having to learn this DNA right along with everybody else.
I really appreciate all the hard work you have been doing recently on
behalf of these Sampson County Carrolls by contacting prospective DNA
donors. I know you have also worked with Jim Carroll, and he is
really making progress on the GA Carrolls who are descended from one
of these.
Keep up the good work,
Lura

Lura,
You sound like a bloomin' SCIENTIST!!! (or Geneticist!).
Jim is going to order a DNA kit for David Wayne Carroll, descended
from a
different line of William B. than is Carl.
I'm going to call the Curtis Victor Carroll I found in Texas tomorrow
and
verify that he will do the test. He is the one who is related to
Donald
Edward. I'm hoping he will agree. He is 80 years of age.

You folks aren't sharing very much regarding DNA recently.
If you have been to
http://www.familytreedna.com/(c1unxwvjnrr3oebovhuard3e)/public/carroll/in...
or to
http://www.childtalk.com/History/carrollfamilydnavalues.pdf
you have seen that the orange band in the middle is growing.
The men who are matching here all have known or strongly presumed
ancestors
from Sampson County, NC, except one. Kit # 19059 can only find
lineage back
to SC in 1808.
Four of these men have now completed the 67 marker test and match at
least
64/67. There will be one more 67 marker test soon. There is one
factor
besides the comparison of markers that makes me think those four are
definitely related. At DYS 425 all four of these men have a null
value. In
other words, they have no repeat of a given pattern of the proteins at
that
location on the DNA strand. The footnote explaining that locus on my
cousin's report from FTDNA stated:
" ***A value of 0 for any marker indicates that the lab reported a
null
value or no result for this marker. All cases of this nature are
retested
multiple times by the lab to confirm their accuracy. Mutations causing
null
values are infrequent, but are passed on to offspring just like other
mutations, so related male lineages such as a father and son would
likely
share any null values."
I believe that there is no question now that these four men have a
common
ancestor, although we still don't know who he is. The goal of our
loosely
organized study group has been to learn how the 10 families in Sampson
County at the time of the 1790 census are related to each other. Some
day
we will, and a blank spot on the DNA is going to help us.
Now, a question - - Have any of you seen another DNA report which
contained
a value of 0 or just a blank box at any location?
