Your therapist sounds like someone who can take care of herself. I wouldn't say anything. On the other hand, the benefit in telling her is that you can unburden yourself and maybe get at why you want to know these things about her. I can sort of understand how you might come across personal information if you were doing a search prior to seeing her, but a no contact order is not something that tends to pop up with a google search of therapists. You know best, but it seems there is something worth exploring there.
