On Family Tree DNA one can 'triangulate' for 'in common matches' (not necessarily in common on the same chromosome). But at least with that helpful hint I can quickly look at those people to see if they match on the same chromosome. Does 23andme have a similar tool? Or do folks all download the data from www.dnagedcom.com so they can manually review which people match on a specific chromosome? I am aware Family Inheritance Advanced lets you compare 3 people to another but that doesn't tell you who ELSE in the list might share that same chromosome location. I'm much more familiar with FamilyTree DNA so perhaps I've missed the tool on 23andme. Denise
