RUSSELL Y-Chromosome DNA Surname Project
The goal of the RUSSELL Surname Project is to distinguish between RUSSELL ancestral lines, not just in the United States, but worldwide. Any reasonable spelling variant is included (see list above -- and please feel free to suggest a variant that I have missed).
Please note that, at the outset, it makes sense to "cast the net widely." As the number of individuals tested increases and various lines become well defined, I will be more than happy to turn over these lines to other researchers specializing in them. I don't recommend splitting-up the project at the outset because I have a feeling we are in for some surprises with regard to where the divisions belong...
