We now have 4 members with results. What do these results mean? As you can see, we have 3 different haplogroups represented so far: J2, I1a, and R1b1
This means that most of us do not share a common ancestor within tens of thousands of years.
However, S-3 and S-4 are both R1b1, and have a genetic distance of 2, since marker DYS390 is off by two. There is at least a 68% chance that these two share a common ancestor within the last 24 generations (about 600 years). I am still learning much about this, so I will post more later. But the FTDNATiP report notes the following:
These results can be refined if their paper trail indicates that no common ancestor between [S-3] and [S-4] could have lived in a certain number of past generations.
I can re-run the FTDNATiP calculator once we have this information.
Also, a better estimate would occur if member S-4 were to upgrade to more markers.
