I remember during one of the live streams or something like that they a person that is a Faunus/Human hybrid would have very unnoticeable features or may not have any features at all. Considering Raven wears a Grimm mask like other members of the White Fang, it is possible she is a Faunus herself. We also haven't seen any bird-Faunus yet, but I think it was also mentioned they are simply more rare so we don't know what kind of traits they may have.

As far as training Adam goes, there is nothing supporting it, but also nothing against it. I mean Raven was probably in her early 20's when she left Yang so Adam may have only been a small child when meeting Raven for the first time. If they were both members of the White Fang, she may have trained them. The only issue is that Blake has been in the WF all her life, so she should know about Raven either from Adam or simply from her being a strong member of the WF. But she doesn't seem to have any knowledge of her so either Adam never mentioned her at all or Raven is like a black op WF agent that stays out of the public image of the WF, even after they turned violent. Or they simply never met.
