Without that you cannot tell from what you reported whether the two matches to you have any overlap. I'd recommend a many-to-many comparison on GEDmatch done 3 times, rotating who is the compare person to see if you have triangulation. That short of a match wouldn't be enough for DNA triangulation, but if they do match there, it adds to your confidence of the 3-way relationship.Ĭomparing Kit A057545 (phyllis berger) and LX175421 (Sam and Ida Bresnick 4cM)Įstimated number of generations to MRCA = 3.5Ĭomparing Kit T543839 (Gaile Connolly) and LX175421 (Sam and Ida Bresnick 4cM)Įstimated number of generations to MRCA = 3.8Ĭomparing Kit A857797 (Brian Bresnick) and LX175421 (Sam and Ida Bresnick 4cM)Įstimated number of generations to MRCA = 4.2 It will be interesting to see if they match each other on that short stretch of chromosome 16 ( 10,794,324 to 12,700,640) where you have matches with both of them. One more thing you might want to do is run the Brian-to-Phyllis comparison at a lower matching threshold than Gedmatch's 7-cM default threshold (for example, try 4 cM). All need is Phyllis' genealogy to help you work out the details. My hunch is that Phyllis is a third cousin to you and third-once-removed to Brian. In each case, the match involves no more than about 1 percent of the person's DNA - when you think about that, there's not a particularly high probability that three people would have received the same little bits of DNA from one particular 2G or 3G grandparent. The fact that the three of you all match each other on several "long enough" chromosome segments is a very strong indication of a common ancestor. Please see the profile I made for Phyllis' grandfather for all the information I have dug up thus far.ĮDITED to correct the match between Brian and me, which was incorrectly stated as at ftdna - it's at gedmatch. I have attempted to contact Phyllis' profile manager and also started to build Phyllis' family, but can't connect Phyllis' mother to the parents and siblings I added because of privacy. Would it be correct to expect Phyllis to turn out NOT to be related through my paternal grandmother, because of the divergence of these two matches? Brian is related through my paternal grandmother. It looks to me like there is only 1 very small place where these two matches have any overlap. Someone else also shows at as a match with the following result: ChrĮstimated number of generations to MRCA = 3.9 At he shows up as a match with the following results: ChrĮstimated number of generations to MRCA = 3.3 I have a known 2nd cousin once removed, Brian Bresnick.

I'm just starting to learn how to use DNA results and I'm afraid that I don't know what I'm talking about.
