About us

The McDuffie surname project has grown to include over 300 members.
Advanced STR and SNP testing has helped refine members results and has given more clarity to the different groups within the project.
It is an exciting time to be involved in genetic genealogy, as the project membership grows and more advances in genetic testing are made, the more we are able to understand our past and where our ancestors originated from.
If you haven't done so already, please update your oldest known paternal ancestor information on your "My Profile" page, and also upload your gedcom under the new "My Family Tree" button located on your home page.

Project members are encouraged to view and join other Familytreedna projects that might be of interest to them, some examples include:
