FTDNATiP™ is unique in allowing you to incorporate your assumptions (based either on a solid genealogical paper trail or an informed guess on your part) on the earliest possible generation of a common ancestor into the DNA match calculations. For example, if you can exclude any chance of a common relative between you and another individual within (say) the past 3 generations, you enter this information, and FTDNATiP™ computes the time to common ancestry based on both the marker pattern and your assumption that the common ancestor must be at least 4 generations back.
