Cloud's Transitive Principle of Kinship: *
          If Alvin is related to Bruce, and Bruce is related to Carl, then Alvin is related to Carl.
 
This definition is modeled after the mathematical Transitive Principle of Equality:
          If A = B, and B = C, then A = C.
 
*  Definition by Tom Cloud as a joke, but it is a practical expression
of the application of dna data in genealogical research.
