Any guesses on which 9 people? [spoilerless]

Iirc in an interview the creator said that Ray revealed the fact that he's Isabella's son to 9 people, but didn't elaborate on who. I don't think Norman and Emma know (which is... Shocking to say the least) and if we eliminate Isabella herself that that leaves 8 people, which to be honest is quite a lot.

​

Any guesses/ theories on who they might be?
