Dear Bill, Yes, I am recommending that all serious autosomal genetic genealogists test at 23andMe. You simply can't afford to miss any of your high quality matches and you will get a lot of them at 23andMe. You won't necessarily have an easy time getting the pedigree charts from all of your matches there, but sometimes you can figure out a match's pedigree chart if they have an unusual name even if they don't do anything other than opt in to open sharing. Keep in mind that to do optimal triangulation, you need the matching segment data AND the pedigree charts from as many people as possible. You only need to have one set of results in Family Finder. I think that it makes sense for the serious autosomal genetic genealogist to do the Family Finder test for all of their close family members because testing at FTDNA gives you the full set of SNP data from the Omni Express chip. This optimizes the probability that the matching segment data will be consistent the most of the other people in the Family Finder dataset. What we don't know at this point is if FTDNA will eventually be moving over to the GSA chip. In terms of uploading to GEDmatch, I would upload a 23andMe version 3 file if you have it since that dataset has the largest number of autosomal SNPs. Otherwise, I would suggest uploading a Family Finder and/or an Ancestry.com dataset to GEDmatch. If you do the 23andMe version 5 test then you will upload to the GEDmatch Genesis project where your results will be compared to other 23andMe version 5 kits and to Living DNA kits. If you already have a Family Finder kit in the regular GEDmatch, then you can simply leave it alone. You won't upload 23andMe version 5 test results into Family Finder unless FTDNA switches to the GSA chip, at which point in time FTDNA might allow that.

Tim, are you recommending that "all serious autosomal genetic genealogists test at 23andMe"? So then, if you upload your 23and Me results to FTDNA, where you have already tested, or to Gedmatch, which already has your Family Finder results, are there any conflicts? One person, 2 sets of results? Bill
