The Culpepper Family DNA Project

Confirm your distant Culpepper ancestry and
help improve the accuracy and reliability
of the Culpepper Family Tree

horizontal rule

Overview. Our project tests the Y chromosome, which is passed directly from father to son, unchanged, from generation to generation. Unchanged, that is, unless a mutation—a random, naturally occurring, usually harmless change—occurs. The mutation, known as a marker, acts as a beacon; it can be mapped through generations because it will be passed down from the man in whom it occurred to his sons, their sons, and every male in his family for many thousands of years.

These mutations establish genetic signatures, called
haplotypes, that define particular branches within a family tree. The haplotypes of tested individuals can be used to confirm, or alter as necessary, the structure of family trees which in the past had to be based on paper-based historical research, family tradition and logical inferences that could be drawn from them.

Project Background and Goals. Warren Culpepper and Lew Griffin, the publishers of Culpepper Connections, launched the Culpepper Family DNA project in December 2006. Utilizing the leading genealogical-genetic-testing company, Family Tree DNA, our goals are as follows:

  1. To confirm, or modify, as appropriate, the structure of the Culpepper Family Tree, giving Culpepper / Culpeper / Colepeper family members the most accurate and reliable information possible on their lineage and how they are related to others who share their surname.

  2. To secure a sufficient number of project members to confirm our ancestral theories on every major branch of the family headed by a Culpepper born at least 200 years ago.

  3. To protect the privacy of each and every DNA project member. The test results and identities of project members are shown only on password protected web pages, and only if they have granted permission for their names and results to be revealed to others who are close matches. Also please note that the Genetic Information Nondiscrimination Act (GINA) bans employers and insurance companies from denying employment, promotions, or healthcare coverage to people based upon the results of genetic tests.

Why You Should Join. Have you and your family enjoyed the family stories, old photographs, genealogies, and historical presentations at Culpepper Connections? If so, then joining the Culpepper DNA project will help us to improve the accuracy and usefulness of the Culpepper family tree and website for you and your family. It is a way  to leave a lasting legacy to Culpepper family history, and to say thank you to the many researchers who have contributed to its content.

Eligibility. You must be a male Culpepper directly descended from a line of male Culpeppers.

Cost for Testing. $169 for a Y-DNA 37-marker test. (The funds for our free testing program have been exhausted.)

How to Join. Go to the Family Tree DNA website

Testing Process. When you join the project, a small packet will be sent to you by the testing lab. You swab the inside of your cheeks a few times, put the swab in a tiny tube they supply, drop it in the pre-paid return envelope, and you're done.

Project Results. Thus far, the DNA tests have confirmed that over 90% of those in our project are members of one of the main lines of Culpeppers. In the process, the subtle details of their Y-DNA test have improved the accuracy of the Culpepper family tree and our knowledge of how we are related to each other. For more information, see our detailed description of our project's results to date, including the branches identified: Project Results (Narrative)
