If they don't appear in the portal then you have already convinced them, so you need to go to the handling room to give the girls their rooms.
How did you even find a comment from a year ago. Don't want to know how far you scrolled. Anyway if you don't have the handling room you need to fix the house first. Explore the house if you haven't, and if you are looking for the etheria you didn't listen to what maeve told you, so go back and replay that event
