Bondurant DNA Project

The BFA Bondurant surname DNA project was announced by project coordinator Amy Warren Sanders at the 2008 annual meeting in Midlothian, VA. The reason for initiating this project was to attempt to develop connections to the children of Jean Pierre Bondurant and his wife Ann Tanner for those “orphan” lines for whom Virginia records could not be found.
Initially, we targeted men with the Bondurant surname, asking them to take the Y-DNA test offered by Family Tree DNA ( Anyone who wished to add their DNA results to the project database was welcome. To date (April 2018) we have 34 members in the Bondurant surname project on FTDNA, but there may be more Bondurant descendants who have tested with other companies and not shared their data with us. Please email your editor at if you want to be added to the Bondurant DNA project.
The AUTOSOMAL DNA TEST was introduced several years ago and provides more opportunities for possible matches than Y-DNA and mtDNA alone. If you are planning to do a DNA test, we would recommend starting with the autosomal test. Many DNA companies periodically offer significant savings on their tests - check their website for more details. Please share your results with us so that we can expand the BFA database further. Your individual results will be held in strictest confidence.
More information about the various DNA tests and testing companies can be found below.
Autosomal Test – examines DNA inherited in a person’s 22 pairs of autosomal chromosomes, but not the sex (X & Y) chromosomes. Tests are available from FamilyTreeDNA, AncestryDNA, MyHeritage, 23andMe - prices may vary, especially near Mother’s Day, Father’s Day, and Christmas. The autosomal tests indicates possible relationships based on Shared cM (centimorgans) and the longest block. (See more about cM later in this issue.)
NOTE: The autosomal tests from the National Geographic Genographic Project (Geno 2.0) and Living DNA do not offer genetic matching, just ancestry composition (formerly called “admixture”) and haplogroup.
Y-DNA Test – examines the DNA found only on the Y chromosome (male) which is passed from father to son in the direct male line (see blue blocks below).
If you are looking for DNA results from a male who is NOT in the direct line (as in maternal grandfather), this test does not help! Use the Autosomal test instead.


mtDNA Test – examines a small segment of DNA that is passed down from the mother unchanged to both male and female offspring. This test can be taken by both men and women. The mtDNA inherited by a son is not passed on to his children. A perfect mtDNA match indicates a common maternal ancestor.

Blaine Bettinger, Ph.D., J.D., a nationally known genetic genealogist, has an excellent series of webinars on DNA genealogy available at The webinars are free to listen to online, but you will need a Legacy membership to download the handouts that go with the webinar. He is the author of several books on using DNA in your genealogy research, including the Guide to DNA Testing and Genetic Genealogy. His blog, The Genetic Genealogist, can be found at
Only FamilyTreeDNA and MyHeritage tests are sold world-wide - see info below for the limited areas for other testing companies. WATCH FOR DISCOUNTS ON KITS around Mother’s Day, Father’s Day and before Christmas. Kits make splendid gifts and help the family to gain knowledge of their kinfolks. We will post information about kit discounts on the BFA Facebook page – at the time of this issue, both FTDNA and AncestryDNA are offering significant discounts. See their website for details.
FamilyTreeDNA (FTDNA) - – sold world-wide There are various prices for Family Finder (autosomal), Y-DNA (males only) and mtDNA (mitochondrial or DNA inherited through mother) tests. The Bondurant Family Association DNA project has used the Y- DNA tests from this company since 2008 to attempt to develop descent from the sons of Jean Pierre Bondurant for orphan lines. Now we are working with AUTOSOMAL tests to broaden our connections within the DNA database. Join the Bondurant surname project to have your results shared with the project
coordinators Amy Warren Sanders and your editor. Results are held in strictest confidentiality.
Cells from the inside of your cheek are collected on a small brush and returned to the company for analysis. No spitting required. (This is especially helpful for testing older members of the family who might have difficulty producing enough saliva as required by other testing companies.)
The Family Finder autosomal test allows you to find relatives based on matches with the 22 non-sex chromosomes in your DNA. Since autosomal DNA may change (or recombine) from one generation to the next, the term “centiMorgan” (cM) is used to show the percentage of possibility that a particular segment of DNA will remain the same or recombine within one generation. The higher the percentage of cMs in a match indicates closer kinship (see centiMorgan chart below).
The autosomal raw data file from 23andMe or AncestryDNA can be uploaded to the FTDNA database FREE to look for even more matches. Instructions and more details on using the Family Finder Matrix to find your matches can be found on the Autosomal Transfer page of the FTDNA website.
The Y-DNA test examines the Y-chromosome (male only) that is passed from father to son, for 37 to 111 markers (see pricing on website at to identify inherited DNA through the direct male line. BFA has used this test to try to determine connections for men in “orphan” lineages to one of the sons of Jean Pierre Bondurant and his wife Ann Tanner: John, Peter and Dr. Joseph.
The mt-DNA test uses the mitochondrial DNA that is passed down almost unchanged from a mother to her children to determine kinship, haplogroup and ancient origins through the maternal line.
AncestryDNA – $99 (watch for discounts) – Autosomal only Sample of saliva (spit) is analyzed to show where your family came from (a comprehensive list of 360+ ethnic regions can be found on the website). Your results also are compared with results from over seven million living members to reveal possible matches – BUT it’s up to you and your possible matches to
determine how you’re kin.
Ancestry does not offer either the Y-DNA or mtDNA test. Your raw data file can be downloaded, saved

to your computer, then uploaded to the FamilyTreeDNA database free. This may increase the number of family matches for you.
You may choose to link your DNA results to an Ancestry online Family Tree, but the test can be linked to only one online tree at a time.
AncestryDNA tests are sold in the US, United Kingdom, Albania, Armenia, Australia, Austria, Belgium, Bulgaria, Canada Croatia, Cyprus, Czech Republic, Denmark, Estonia, Finland, Georgia, Greece, Hungary, Ireland, Liechtenstein, Lithuania, Malta, Netherlands, New Zealand, Norway, Poland, Portugal, Romania, San Marino, Slovakia, Slovenia, South Korea, Sweden, Turkey, and Vatican City.
23andMe - – $99 for ancestry & Relative Finder only; $199 for ancestry, Relative Finder, inherited traits and genetic health risks – Autosomal
Sample of saliva (spit) is analyzed to show ancestry composition (percentage of descent from over 150 regions), maternal and paternal haplogroups, with optional Relative Finder matching.
The full report examines your genetic risk for diseases such as celiac, late-onset Alzheimer’s, and Parkinson’s; whether you might be a carrier of cystic fibrosis, sickle cell anemia or hearing loss. Inherited traits such as hair loss, freckles, hair texture, dimples, sweet vs. salty taste, eye color, etc., are reported in the full test. Raw autosomal data can be downloaded as a file and uploaded to FamilyTreeDNA’s database free. See FTDNA above.

MyHeritage DNA – $69 (sale price) plus shipping - sold worldwide This test uses a swab to gather cells from the inside of your cheek. No spit or blood required. Create a
free account to upload your raw data from other testing companies. The test results show ethnicity estimate and DNA matches. A chromosome browser is available on the
website. A family tree building program is offered, but with a limit of 250 relatives under the free basic plan. To access their database of historical records, advanced DNA features and Smart Matches, four subscription plans with annual fees from $85 to $180 are available (in addition to the cost of the DNA test). See the pricing plan link at the bottom of the page.
Ethnicity estimates are based on matches to unique DNA sequences from 42 Founder Populations - a database developed by MyHeritage using populations who have lived in the same region of the world for generations, thus their DNA is highly characteristic of the region.
A new program launched this year by MyHeritage is DNA Quest, a pro bono initiative to help adoptees reunite with their birth families. See for more details.
All testing companies listed here do not sell, lease or rent individual results to any third party. They may, however, share aggregate information from which your individual details have been removed, for research or to improve testing. When you share your results with the BFA DNA project, we pledge to hold them in strictest confidentiality, too.
Personal information (name, contact, etc.) is assigned a random customer ID number; and is typically stored in physically separate computing environments from your genetic results, using software, hardware and physical security measures to protect your information. If you share your information with others, this security cannot be guaranteed.
The only company offering genetic health risk testing is 23andMe, who have pledged not to provide any person’s data (genetic or non-genetic) to an insurance company or employer.
The Genetic Information Nondiscrimination Act (GINA) of 2008 is federal legislation designed to protect Americans from discrimination in health insurance and employment decisions on the basis of genetic information,. BUT this act does not cover life or disability insurance providers!
These entities do not perform genetic testing, but provide additional opportunities for genetic matching with others when you upload your own genetic information to their databases. Results from some companies may not be compatible with these databases, which are indicated below.
