There's a difference between "contacting her family," haphazardly, and a planned, comprehensive intervention/exposure. But you're correct -- DB is anti-exposure. I happen to disagree with that, for a variety of reasons. I"d suggest getting the pro's and con's and making your own decisions.
I'd advise to either do it, thoroughly and the right way, or don't do anything at all. Informing the other family isn't something you want to dabble in.
