not-usual townies showing up in Sunset Valley before playing

I did, yes, but it still wouldn't make sense? These sims aren't from that save or something.

And probably not but I'm not gonna try it as I already started playing and sims takes a while to start up. I can't just quit the game and load it again to test hosueholds that don't really bother me extremely. I came to the conclusion by the way these are in fact the sunset valley ghosts: the darling household is Agnes Crumblebottom's deceased husband.
