You can use the Ancestry groups in a similar fashion. Create four groups. (or more) using their color dot codes. Leeds stresses that you work with 2nd cousins matching between 70cM to 200 cM. Go to your first match, select the match, and then shared matches. Use the group 1 color and add all these shared matches to the group. Go back to dna matches and look for the next match that is not in group 1. Repeat the process with the new match using group 2.
Dana has a blog and website and you should be able to watch a video on her method, perhaps on Youtube also Good luck
