Going to contact my brother and ask him about it. He is my half-brother, and he is related to them through his late father (my step-father). Maybe someone on his father's side of the family has something to say about this Documentary. Actually all of my siblings are related to them, since I am the only one with a different father. Me being the oldest and all. So that includes the sister I raised, but my Brother is the one who still makes a lot of trips back and forth to L.A. and is probably the better source to ask.
