There was a novel[1] about a woman with DID and a psychologist who tied that to suppressed memories of sexual abuse. I wondered after reading it whether or not it was a thing or just a creative fiction. I found at least one paper [2] which indicates that DID can be a symptom of prior abuse.
Note that the concept of 'suppressed memories' is not very well accepted by the psychological community. People can be convinced that they remember something they don't, so it's extremely difficult to tell between a 'suppressed' memory and a false one.
