I will assume that they don't know until the series proves me wrong.

I mean, even though they apparently didn't know that the White Fang was at the Fall of Beacon, they didn't react with surprise when they were told that Adam was leading a splinter group, despite the fact that he used to date their daughter.

Personally, I see something along these lines happening:

Kali: ...Wait, Blake, didn't you used to like that guy?

Sun: (Spits drink).

Blake: Actually, I kind of used to...date that guy.

Ghira: What?
