FTDNATiP™ allows you to incorporate your solid genealogical paper trail information 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 three generations, you enter this information, and FTDNATiP™ computes the time to common ancestry based on both the STR marker pattern and your information that the common ancestor must be at least four generations back.

Why did the FTDNATiP™ probability become less when we eliminated the possibility of a common ancestor within the past seven generations? It seems that it should increase?

When comparing two individuals, the DNA test shows them to be closely related. However, one has my surname and the other does not. Does the match with the similar surname mean we are more closely related?
