DNA Testing and Mx Genealogy: The Molyneux Surname Project.
By Steve Mullinax, US 312
IMFA considers DNA testing and the Y-DNA Surname Project to offer significant opportunity
to further our knowledge of the various branches of MX families and how they interconnect.
Your participation is critically important.
About 100 Mx men, including many IMFA members have had their DNA tested, to apply
Y-chromosome results to their study of Mx genealogy. According to researcher Chris
Pomery, "DNA testing is proving an effective tool to corroborate the integrity of
documented family trees for the simple reason that the DNA [Y-chromosome]
signature of each male descendant is passed down from father to son in a manner
that exactly mimics the transmission of the surname from one generation to the next."¹
Your DNA test results cannot, without a paper trail, tell you who your gx-grandfather
was. How can it help with your genealogy?
IMFA has a Molyneaux "surname project". According to Genetic Genealogist Blaine
T. Bettinger, Ph.D.²:
A DNA project is a collaborative effort to answer genealogical
questions using the results of DNA testing. A surname project brings together individuals
with the same (or very similar) surname, … DNA projects are run by Administrators
who are responsible for organizing results, sharing information, and recruiting
new members to the group. DNA projects can potentially provide a number of benefits
to participants, including the following: [I’ve selected the ones below because
they seem to me the ones most relevant to IMFA. SM]
- Confirm or reject suggested relationships between individuals in the project;
- Identify previously unknown relationships between individuals in the project;
- Confirm or reject the relationship of particular surname lines or surname variants
(for example, do the Molyneux and Mulno surnames have a common source?);
- Identify or learn more about the surname’s country of origin;
- Learn more about the ancient ancestry of a surname and its variants;
- Learn more about the migration of the surname over time;
- Join a community of exciting genetic genealogists.
Here is an example of the DNA test results identifying a previously unknown relationship.
Sharon Bryant, who organized and administered the surname project prior to her death
in 2008, reported in December, 2005:
The exciting news is that we had a 37/37 match between one of our English participants
and a descendant of Greenbury (IN>MO>IA). This match, which means that all 37 markers
tested for each of them are identical, indicate a definite connection between an
English Molyneux family and the Mullinnix family here in America.Sharon Bryant
According to the testing company, Family Tree DNA, a 37 of 37-marker match indicates
a 95% probability of the Most Recent Common Ancestor (MRCA) being no further back
than seven generations, so the DNA test is pretty solid evidence of a recent ancestral
connection. But there is still work to be done, as Sharon wrote, "Now the trick
is to find the paper records that cement the relationship and to determine actually
what the relationship is." Knowing from the DNA that there is a recent male ancestor
connecting these two families is useful, in that it tells us that conventional research
may bear fruit. It points us in the right direction, but it does not answer the
more specific question of who the common ancestor is. (I don’t know whether these
two researchers connected their paper trails.)
Status and plans for the Molyneaux Surname Project.
Three IMFA members are now collaborating to reorganize and administer the project:
Jim Molineux (US 329), Wayne Straight (US332) and myself, Steve Mullinax (US 312).
Based on interest among participants, we will initiate a project to:
- Corroborate and/or find errors in documented family trees. Researchers may use any
errors discovered to correct or find additional documentation for the relationships.
- Identify documented family trees that share genetic signatures but for which no
documented connection has yet been established. Researchers may then choose to pursue
documentation of the connection.
- Reconsider documentary research efforts on lines which have no genetic connection.
- Suggest which family lines would benefit from added genetic testing, to corroborate
or refute documented connections.
We look forward to working with IMFA members and other Mx researchers.

How You Can Help
If you have been tested, it is very important that you post your pedigree.
If you have not posted yours, please do one or both of the following:
- Enter your pedigree on our website at Lines &
DNA/Enter Your Pedigree.
- Email your pedigree (or a GEDCOM file) to our webmaster at
We would appreciate hearing from you about any of the following, or about anything
else you want to bring up.
- What information regarding the surname project would you like to see available online?
What are your suggestions about the best way to present this information.
- Give us any feedback you have about how the available online tools have helped or
hindered your study. How could these tools be improved?
- Give us any conclusions they were able to reach using test results. We expect the
revitalized surname project to be of great benefit. It will provide researchers
a platform to collaborate with others on the project to discover new relationships,
help consolidate fragmented trees and guide conventional research.
Who Should Test?
While we would like to see every one of our male members participate we have given
special importance to filling the holes in certain lines. These specific lines represent
missing pieces to the puzzle that will show the big picture of how the various Mx
lines we have identified relate to each other. See if you might be one of our
high priority testing candidates
that could provide a very valuable service to your Mx cousins.
Y-DNA37 test description
Family Tree DNA offers a
variety of DNA tests. IMFA recommends the Y-DNA37 test which typically costs $99
after member discounts. Tests with fewer markers are available but are not definitive
for genealogical purposes.
This is a male specific test. Results identify the ethnic and geographic origin
of the paternal line. It includes a balanced panel of thirty-seven Y-chromosome
Short Tandem Repeat (STR) markers. This is the recommended test to trace the paternal
ancestry of males for genealogy purposes. The additional markers refine the predicted
time period in which two individuals are related and eliminate unrelated matches.
A perfect match at thirty-seven markers indicates the two individuals share common
ancestry in recent times. When another person shows identical results within the
FTDNA database, and if both parties have signed the FTDNA Release Form, then FTDNA
will inform them of the match. You will also receive a certificate and report describing
the testing process and the meaning of thirty-seven marker matches.
Testing is Easy!
FTDNA DNA Test Kit Instructions
A Family Tree Tree DNA test kit consists of two cotton 'toothed' swab kits, designed
for a single persons use. Each tube contains a fluid designed to arrest bacteria
growth, so you can scrape your cheek and return your kit in any type of weather
(hot or cold). The freshness of your sample will remain intact for months. Remember,
a good scrape produces lots of DNA.
Your kit also includes instructions for collecting your DNA sample (available in
many languages) and the all important Release Form. The Release Form is your written
consent that allows FTDNA to share your name and email address with our Molyneaux
DNA Surname Project or someone who matches your genetic fingerprint exactly.
Special Group Pricing
Joining our surname project at Family Tree DNA will allow you to get special group
pricing. View complete information and pricing on their current offerings: > Join or View Our Family Tree DNA Group.
Only by ordering through the surname project can participants receive the group pricing.
If you have already tested with FTDNA you may request, via e-mail, that your results
be transferred to the Molyneaux Surname Project. If you are not sure how to go about
that contact FTDNA or email our DNA Surname Project Coordinator at
email@example.com, include your name and kit number and I will request the
IMFA Member Testing Grant
Through the generous donations of IMFA members there are a limited number of $50
grants available to IMFA member's to reduce the cost of your test. IMFA considers
DNA testing and the Y-DNA Surname Project to offer significant opportunity to further
our knowledge of the various branches of MX families and how they interconnect.

Ther DNA Test Types
In addition to the Y-DNA test used in our project there are two other common DNA
- Autosomal DNA (i.e. Family Finder, 23andMe) attempts to find cousins on both
the father's and mother's side within the past 5 generations. This compares to the
Y-DNA test used in our surname project which looks back 25 generations or more at
the male line only.
- mtDna traces the mother's mother's ... line and provides no information about
the father's line. Hence this test is not useful in a surname project.
