Possible Relationships Calculator

Enter the amount of shared cM of DNA (or percent of DNA) with your match.  This amount comes from your match list at Ancestry, FamilyTreeDNA, 23andMe, or GEDMatch.  Based on the shared amount of DNA, you will receive a “group.” The possible relationships for each group are shown in the table below.  Possible relationships are provided by DNA Detectives.

Please note that the percent portion of the calculator needs to be updated; however, the cM portion is working.

DNA Hunters offers several DNA-related services.  The Learning Center provides more information about DNA testing for family research.
