Question about the house, does the lanlord know? And are the demon's origions come from it, or did they find it, then get bound to it

The Landlady does know; her name is Ms Ross (Marie Ross) and I am going to play as her when she is interacted with. I don't really want to say too much about her relationship to the house and the demons as I feel like it would be better for plot and character development that this stays a mystery till later on, however, I will say that the house has been in her family for many decades. 
The demons in a sense did find the house and were the bound to it, but they don't have much memory as to who bounded them or how long ago this was; since the demons don't need to sleep (unless they prefer to) the days and years that go by merge into one long expanse of time.
