Keep in mind that "multiple histories" is (in a way) the time-reversed view 
of "many worlds":

*In the same way that the many-worlds interpretation regards possible 
futures as having a real existence of their own, the theory of multiple 
histories reverses this in time to regard the many possible past histories 
of a given event as having real existence.*

Fay Dowker [ https://en.wikipedia.org/wiki/Fay_Dowker ] gives a short 
summary of "sum over histories" here (and why she prefers it to other 
interpretations).
