Background

The Administrator of this project, Rebekah A. Canada, will be on vacation through November 30, 2012. For questions about DNA and your personal ancestry, please see the Family Tree DNA FAQ/Knowledge Base. Additional questions may be sent to Family Tree DNA Customer Service.

The DAHL surname and its variants (Soundex D400 and T400), may be found throughout Northern and Western Europe. Further, by 1900 the name could be found among those of African American and Native American ancestry. Today there are many different DAHL lineages. The DAHL Surname DNA project is dedicated to using DNA and the tools of genetic genealogy to distinguish each lineage.

As a surname project, the primary tool is the Y-chromosome DNA (Y-DNA) that is passed down from father to son in much the same way as Western European surnames. The Family Finder autosomal DNA test may also be used to compare two individuals who are related within six generations. The Dahl (D400) Surname Project welcomes all who wish to trace a DAHL ancestor without regard to nationality, race, or creed. We welcome those who are adopted whether you have the DAHL surname today or suspect that your birth father was a DAHL.

Joining The DAHL Surname Project

If you are interested in joining the project and you have not yet tested through Family Tree DNA (FTDNA) or one of their affiliates, you may do so by ordering a Y-chromosome DNA (Y-DNA) or a Family Finder (FF) test.

                           
                           
                           
                           
                           

Y-chromosome DNA (Y-DNA): Y-chromosome DNA (Y-DNA) testing is the proven method to find and prove genealogical connections between men using genetic technologies. Matching and partial matching combined with traditional genealogical research effectively demonstrates relationships for 1 to 15 generations. For most researchers who have reached a brick wall in their genealogy, this is the ideal test.

For successful comparison and matching, you should order either a Y-DNA37 or Y-DNA67 test. This is sufficient resolution to ensure that your matches are not coincidental. Because Y-DNA is inherited only by men, the person tested needs to be a male with the DAHL surname (or variant). In the case of an adoption, the man tested should be the biological son of or paternal grandson of a man with the DAHL surname. Contacting males with the DAHL surname (brothers, fathers, uncles, cousins, etc.), is often required.

                           
                           
                           
                           
                           

Family Finder (FF): The Family Finder test is a new way to find genetic connections that support traditional genealogy. It uses your autosomal DNA to match you with cousins within six generations. These matches may come from any of your 32 great-great-great grandparents. They will include both your male and female relatives and anyone may take the test.

Because the Family Finder test is new, you will need to reach out to potential matches from your suspected line asking them to also test. They may be of either gender, and it does not matter if their relationship to your common ancestor crosses back and forth between male and female lines. It is important that they be related to you within six generations.

If you have already tested with FTDNA or an affiliate (National Genographic, IGENEA, African DNA, etc.), you may join the project using your existing results.

Donating to the DAHL Surname Project

The DAHL Surname project has a general fund to which you may contribute. You may donate to all testing efforts, or you may specify the kit or lineage for which you would like to pay for testing. Should you donate to a specific kit, I will do my best to obtain consent for the upgrade from the owner of the kit.
