Hi David, I have seen this used quite successfully in the past. This is when you send an email to those involved and see if you can find some common ancestors or at least common places of origin. I suspect that this grouping is a good indication of where the relationships might be. In other words, this then becomes a head start for the paper trail genealogy. Sarah Christiansen
This weekend I decided to use FtDNA's chromosome browser to compare my 22 third cousin hits and found some, to me, intriguing results. I found 3 people who share almost exactly with me an apparently significant stretch of chromosome 2. All three of these show the exact same similarity endpoint. Two of those same people appear to share exactly the same 16.81 cM region with me.
