Cox DNA Project
We currently have two distinct Cox DNA
subprojects.
The Cox/Coxe/Cock/Cocks/ Project at FamilyTreeDNA
(https://www.familytreedna.com/surname_join.aspx?code=R71042&special=true)
This surname project uses yDNA test
results from men that descend from the Cox (or name variant thereof)
line to identify relationships among distant Cox lines. It is
managed by 3 administrators; Margie Romine manages the Brandywine
subgroup while Terry Barwin and Charles Cox manage the remaining Cox
testers. All three work together to review the results and keep up
to speed on new technologies for analyzing the data.
As of October 2022, we have 90 men that
have taken the test and group with descendants of the Brandywine
Coxes. The project also includes numerous other Cox lines that are
distinct from our line.
The majority of our testers have taken
only the classic yDNA tests that count tandem DNA repeats in select
regions of the yDNA chromosome (Y12, Y25, Y37, Y67, or Y111). Using
the test results, along with family lines provided by these testers,
we were able to identify many family lines that belong to the
Brandywine group, reaching back to the mid-1600’s when the first
member of our line came to America.
There remain many questions regarding
precisely how these lines connect, so we have begun encouraging our
existing testers and others to upgrade to, or take for the first
time, the BigY test also offered by FamilyTreeDNA. This test is
different than the classic tests in that it allows you to determine when your
most common ancestor is another tester lived (within ~100 years of
the actual date).
As of October 2022, we have 12 BigY tests
completed with two more under way. Of these 14 tests, 11 are from
descendants of Solomon Cox and Naomi Hussey and two from William Cox
and Catherine Kinkey.
We are actively searching for males that
descend from the siblings and ancestors of Solomon Cox (1738-1820)
as well as any new children of Solomon that we may discover (see
below) so that we can test alternative hypotheses regarding the
ancestor linkages to Solomon Cox 1738. See
BrandywineMaleLine.pdf
for an alternative hypothesis on early Cox male ancestors that
differs from what we currently have in our Cox database.
BigY testers needed:
Descendants of Solomon Cox 1738 (m. Naomi Hussey)
1.
A second tester that descends from Solomon Jr
1761 (m. Martha & Mary Dixon) but not via his son Joseph
2.
A second tester that descends from Absalom
1767 (m. Mary Prigmore & Mary ?) but not via his son Daniel
3.
A second tester that descends from
Christopher 1773 (m. Hannah Johnson) but not via his son Cornelius
4.
A second tester that descends from Stephen
Cox Sr 1779 (m. Mary Robertson) but not via his son John
5.
Two testers that descend from different
children of William Henry Cox 1782 (m. Martha Elizabeth Cantrell)
Siblings and/or Ancestors of Solomon Cox 1738
1.
A second tester that descends from Samuel Cox
1723 (m. Hannah Wierman) but not via his son John William
2.
2 testers that descend from different
children of Benjamin Cox 1723 (m. Martha Garretson)
3.
An additional tester that descends from
William Cox 1692 (m. Catherine Kinkey) but not via his son Harmon
4.
2 testers that descend from different
children of Thomas Cox 1694 (m. Elizabeth Fincher)
5.
2 testers that descend from different
children of William Cox 1725 (m. Naomi Garretson)
6.
2 testers that descend from different
children of Thomas Cox 1730 (m. Martha Jenkins)
Others
1.
At least one tester that descends from
Elkanoah Amos Cox 1792 (m. Nancy Ann Lee)
2.
Male testers of Cox lines with brick walls
The Quaker Cox Surname Ancestor project at Gedmatch
This surname project was started at the
end of 2021 and uses autosomal test results from both men and women
that are direct descendants of our Cox line. We use these results
to validate branches in our family going back to the 1700’s.
As of October 2022, we have 176 DNA kits
in the project. Using data from this project along with a method
called DNA triangulation we identified a candidate new son for
Solomon/Naomi Cox. This son, William Henry Cox, is described in the
Spring 2022 Brandywine newsletter.
We are actively seeking new people
that have had their autosomal DNA tested to join the project.
Our current membership is heavily biased towards descendants of
Solomon/Naomi Hussey. While additional descendants from this
line would be welcome and useful, we are especially interested in
new members that descend from siblings and other ancestors of this
couple to join.
Margie Romine and Tony Cox are
administrators for the project. Joining and use of Gedmatch is
free. They accept results from the major testing companies such as
Ancestry, MyHeritage, FamilyTreeDNA, and 23andMe. For research
purposes, we require that you share your Cox family line as far back
as you know it in order to add you to the project. Information on
how to add you DNA to gedmatch can be found at: https://blog.genomelink.io/posts/how-to-use-gedmatch
Thank you for your interest in the Cox
DNA Project.
