I think it's pratically confirmed Mary from FNAC3 is the same one from FNAC1. In both games she has the origami cat watching over her and she even hallucinates Vinnie in the cutscenes(which looks different because she saw the Puppet in a Freddy's location and her memories of the two mixed together).
