My Daughter and I tested our autosomal DNA at FTDNA and uploaded our results to GEDmatch. Person "A" tested at Ancestry and also uploaded to GEDmatch. That person does not match me on GEDmatch but does match my daughter on Chr7 for 20.1 cM and 3,26 SNPs from position 135,392,982 to 149,214,524. Person "B" tested at FTDNA but has not uploaded to GEDmatch. This person does not match me on FTDNA but does match my daughter on Chr7 for 19.05 cM and 2,978 SNPs from position 138,046,889 to 150,314,016. Is this enough information to be certain that persons "A", "B" and my daughter form a triangulated group? Is it necessary for person "B" to upload to GEDmatch to be certain?

Do you know that A and B match each other as well as your daughter on the same chromosome segment? If they are not both at Gedmatch, you cannot do a one-to-one test to determine this.
