|In the above graph, my father (David) shares genetic material with all three of these people, though not on the same chromosome. This could indicate a shared ancestry among all four of them.|
|The new ability to compare matches against one another enables us to see that C. W. matches N. P, but not R. M.|
|In addition, N. P. does not match R. M.|
From this, we can proceed with the hypothesis that N. P. and C. W. match David on one side of the family, while R. M. matches on the other. We just have not figured out which one is which (yet).
