Corrected post with link to a beta autosomal phasing tool. Note, tool is windows command line. If you are not comfortable with windows command line wait for a later version http://www.exploreDNA.com/files/GenComp1.1.zip Diana, Mary Alice is exactly correct. The match threshold for FTDNA or 23andMe, while reasonable for screening out difficult matches to find and real false positives, is not appropriate for identifying matches between known, or strongly suspected relatives. There are alternatives like Dr Pike's utilities http://www.math.mun.ca/%7Edapike/FF23utils/ Dr Pike's utilities do require having a downloaded copy of the raw data involved. But, the Raw Data is never uploaded. The beta phasing tool in this thread can also be used to examine the Raw Data more closely https://www.23andme.com/you/community/thread/11466/#most_recent www.GEDmatch.com requires uploading the Raw Data Sam
