For people who checked 67 markers, although not, and found an accurate (67 getting 67) matches with someone else, then there is a fifty% options that the couple share a familiar predecessor within this a few generations and you will an effective 95% possibility that the well-known ancestor is during six generations.
More STR indicators, the greater the cost of the exam. If the rates was a significant factor for your requirements, then you may be interested in beginning with an inferior number from indicators, and then revision at a later date when the justified.

Extremely uncommon surnames can see a good influence that have as little as 12-markers.
