You will meet them again after your first interaction with them (Laura's happens automatically, the others you can meet in town - Lucille is in the park at night, I think, and Reneé at the shops..?)
Once you've met them again you can talk to Jessica about moving them into the Manor (I think you need to have built the extra hallway upgrade first).
Sorry I can't be more detailed - I coded all this in about two years ago and I'm not at my computer right now :P
