Frank,
There are two DNA tests presently being used for most genealogical
studies. The Y-DNA test being used for surname projects can only show
a direct male lineage - from a man to his father > his father > his
father > his father, etc. The reason this is true is because the
material being tested is passed via the sperm from a man to his son,
never to a daughter. You cannot take this kind of test to show any
Carroll lineage, since your mother was a Carroll. If you took the
Y-DNA test it would point backward from YOUR father, not from your
mother's father. The Y-DNA test is being used for the Carroll Surname
Project.
The mtDNA test is used to show a direct female lineage. This test
points backward to mother > her mother > her mother > her mother, etc.
Since the surname changes with every generation, this test is not used
today in genealogy as often as the Y-DNA test. A mother passes this
kind of material from the egg to both her daughter and her son.
However, if you took the mtDNA test, it would point to your mother,
her MOTHER, etc.
Both of the above lineages would be broken if there had been an
adoption or other non-paternal event in the family. For example, a
person might have the CARROLL surname but have his DNA not match
others on the family tree, because his grandfather Carroll was born to
an unwed Carroll mother. The DNA is passed by sperm, not by a name.
Some people prefer not to share information about such events. No
information we find changes who ALL our ancestors together helped us
to become.
Frank, I hope this helps answer your question. Try to find
descendants of your Grandfather Carroll's brother to do the test for
your entire Carroll family.
There are many places online where you can get further information
regarding DNA testing. FamilyTreeDNA, an independent company, was the
lab chosen for the CARROLL project as well as over 4,000 other surname
projects. The records from their analysis are available only to the
donor or to those he matches - if he signs a consent form. (I'm not
affiliated with that company, nor was I involved in setting up the
Carroll Surname Project.) They have many pages of information
available at their website for learning more about DNA testing. Try
some of these following sites and click all the links from those.

Not related to FTDNA, Dr. Charles Kerchner and many others have spent
much time and effort to help us understand the biology and science
behind this new field of genealogy. You can link to some of Dr.
Kerchner's material at

Be sure to check the first two and keep the glossary available as you
try to understand DNA testing.

: James,
:
: Has any man in your family with the CARROLL surname sent a DNA
sample
: to the Carroll DNA Project?
:
: We have found so far that at least 6 men are probably related to one
: of the ten Carroll families which were living in the same community
in
: Sampson County, NC in 1790. Three of the men matched perfectly
37/37
: markers tested. This seems almost miraculous considering there had
: been no contact in those families in 200 years.
:
: If no one in your family has been tested, can you locate a man with
a
: direct male lineage with no adoptions or other "non-paternal" event
: back to your John Carroll, born 1660 who would be willing to do the
: test? He would have the CARROLL (or Carrell or whatever) spelling.
: If so, Kevin Carroll, the project administrator,
kushtiqa(a)hotmail.com
: can help answer any questions you may have or you can order the test

: In the drop-down menu at the bottom, choose the preferred Y-DNA67 or
: the Y-DNA37. The 12 and 25 marker tests don't really provide enough
: information.
:
: Since you have such a well outlined family history, it would be
: helpful to have the DNA so others could compare to see if they might
: be part of your family. Who knows? Our Sampson County, NC and your
: York County, SC Carrolls might be long lost cousins.
