Clan Henderson DNA Project results are posted for the benefit of our project participants and members of the Clan Henderson Society. For this reason, our results are identified by membership and DNA kit number rather than by name. You must know your kit number in order to find your results.

When a new Henderson DNA test is recieved, there is a standard process that takes over. Specifically, each new DNA signature is entered into a spreadsheet at a position nearest matching or closely matching signatures of other Henderson members. Over time as new members join, these matching and closely matching signatures begin to cluster. We identify these clusters by an alpha-numeric code starting with Family Group A1. Other clusters closely matching but not exactly matching become Family Group A2 and then Family Group A3 and so on. When we receive a signature that cannot be closely matched to Family Group A, we assign a new identifier, thus Family Group B is created with its own unique line of alpha numeric subsets.

Note:  Even if you have already tested and received your results from the Henderson DNA Project, you may consider having another member of your family tested. The reason you need a second or third sample is that distant cousins who share a common ancestor two or more generations back in time may have slightly different DNA due to fast moving mutations in certain markers. This is the reason we recommend at least two DNA results at the cousin level (not the brother level) to verify the signature of the family line. Once you have the definitive signature of your family line, there is no need for further testing.
