Mukremin's charts are about as good as you can get. The administrations for the respective families are in such a state of flux due to the amount of convictions that it is practically impossible to get an accurate read on any family leaderships. Even with that said, most lower level guys don't even know their family's own administration. They know who they kick up to directly but in this day and age it's too risky for anyone but the biggest earners to know who really runs things.
